These research results belong to Ismael, Ali; Wang, Xintai; Bennett, Troy L. R.; Wilkinson, Luke A.; Robinson, Benjamin J.; Long, Nicholas J.; Cohen, Lesley F.; Lambert, Colin J.. COA of Formula: C14H8Br2 The article mentions the following:

It is known that the elec. conductance of single mols. can be controlled in a deterministic manner by chem. varying their anchor groups to external electrodes. Here, by employing synthetic methodologies to vary the terminal anchor groups around aromatic anthracene cores, and by forming self-assembled monolayers (SAMs) of the resulting mols., we demonstrate that this method of control can be translated into cross-plane SAM-on-gold mol. films. The cross-plane conductance of SAMs formed from anthracene-based mols. with four different combinations of anchors are measured to differ by a factor of approx. 3 in agreement with theor. predictions. We also demonstrate that the Seebeck coefficient of such films can be boosted by more than an order of magnitude by an appropriate choice of anchor groups and that both pos. and neg. Seebeck coefficients can be realized. This demonstration that the thermoelec. properties of SAMs are controlled by their anchor groups represents a critical step towards functional ultra-thin-film devices for future mol.-scale electronics.

《Controlling the structure and photophysics of fluorophore dimers using multiple cucurbit[8]uril clampings》 was published in Chemical Science in 2020. These research results belong to Wu, Guanglu; Bae, Youn Jue; Olesinska, Magdalena; Anton-Garcia, Daniel; Szabo, Istvan; Rosta, Edina; Wasielewski, Michael R.; Scherman, Oren A.. Synthetic Route of C14H8Br2 The article mentions the following:

A modular strategy has been employed to develop a new class of fluorescent mols., which generates discrete, dimeric stacked fluorophores upon complexation with multiple cucurbit[8]uril macrocycles. The multiple constraints result in a “”static”” complex (remaining as a single entity for more than 30 ms) and facilitate fluorophore coupling in the ground state, showing a significant bathochromic shift in absorption and emission. This modular design is surprisingly applicable and flexible and has been validated through an investigation of nine different fluorophore cores ranging in size, shape, and geometric variation of their clamping modules. All fluorescent dimers evaluated can be photoexcited to atypical excimer-like states with elongated excited lifetimes (up to 37 ns) and substantially high quantum yields (up to 1). This strategy offers a straightforward preparation of discrete fluorophore dimers, providing promising model systems with explicitly stable dimeric structures and tunable photophys. features, which can be utilized to study various intermol. processes. In the part of experimental materials, we found many familiar compounds, such as 9,10-Dibromoanthracene(cas: 523-27-3Synthetic Route of C14H8Br2)

Application of 523-27-3 And the article was included in Chemical Science in 2020. The article conveys some information:

Designing a donor-acceptor (D-A) mol. with a hybridized local and charge transfer (HLCT) excited state is a very effective strategy for producing an organic light-emitting diode (OLED) with a high exciton utilization efficiency and external quantum efficiency. Herein, a novel twisting D-π-A fluorescent mol. (triphenylamine-anthracene-phenanthroimidazole; TPAAnPI) is designed and synthesized. The excited state properties of the TPAAnPI investigated through photophys. experiments and d. functional theory (DFT) anal. reveal that its fluorescence is due to the HLCT excited state. The optimized non-doped blue OLED using TPAAnPI as a light-emitting layer exhibits a novel blue emission with an electroluminescence (EL) peak at 470 nm, corresponding to the Commission International de L’Eclairage (CIE) coordinates of (0.15, 0.22). A fabricated device termed Device II exhibits a maximum current efficiency of 18.09 cd A-1, power efficiency of 12.35 lm W-1, luminescence of ≈29 900 cd cm-2, and external quantum efficiency (EQE) of 11.47%, corresponding to a high exciton utilization efficiency of 91%. Its EQE remains as high as 9.70% at a luminescence of 1000 cd m-2 with a low efficiency roll-off of 15%. These results are among the best for HLCT blue-emitting materials involved in non-doped blue fluorescent OLEDs. The performance of Device II highlights a great industrial application potential for the TPAAnPI mol.

The article was titled 《Fine regulation of linker and donor moieties to construct benzimidazole-based blue emitters for high-efficient organic light-emitting diodes》.Reference of 9,10-Dibromoanthracene The article contains the following contents:

The investigation and development of novel blue emitters are still necessary for the fabrication of high-efficient organic light-emitting diodes (OLEDs). Benzimidazole and its derivatives have been attracting extensive attention due to the special characterizations to achieve high device efficiency. However, the systematic elucidation of the relationship between structure and properties is rarely reported. In this paper, four benzimidazole derivatives with virus linker and donor units were designed and synthesized, named PI-AN-3-Cz, PI-NP-3-Cz, PI-AN-TPA, and PI-NP-TPA. Their absorption, photoluminescence, electrochem., and thermol. were systematically studied, and the results were found to be potential candidates for emitters of OLEDs. Interestingly, the fabricated OLEDs with PI-AN-3-Cz as emitter showed the best performance with the efficiencies of 13.75 cd/A, 5.87 lm/W, and 8.55%. Furthermore, it can be observed that these linkers/donors are changed from anthracene to naphthalene/carbazole to triphenylamine, the corresponding emission moved from sky to violet blue with commission international De L’ Eclairage (CIE) of (0.151, 0.055). The findings give a guidance for the preparation of adjustable emission and high-efficient benzimidazole derivatives The results came from multiple reactions, including the reaction of 9,10-Dibromoanthracene(cas: 523-27-3Reference of 9,10-Dibromoanthracene)

The title of the article was 《Controlled, Sunlight-Driven Reversible Cycloaddition of Multiple Singlet Oxygen Molecules to Anthracene-Containing Trianglimine Macrocycles》.Quality Control of 9,10-Dibromoanthracene The author mentioned the following in the article:

Controlled release of singlet oxygen is of interest not only to chemists, but also to biologists and medics involved in cancer therapy. Two chiral polyaza macrocyclic compounds and their corresponding endoperoxides have been synthesized. These peroxides exhibit high temperature stability, up to 80°C. Detailed studies on their structure, including X-ray anal. as well as NMR, UV-VIS ECD spectroscopy and theor. calculations, combined with photochem. measurements indicate that their high stability is related to the arrangement of oxygen atoms in a conformationally stable macrocyclic ring. Despite the change of carbon hybridization from sp2 to sp3 at the 9 and 10 positions of the anthracene units, the macrocyclic skeleton of the obtained compounds does not change its conformation. The obtained endoperoxides can be formed and release singlet oxygen by irradiation with UV light of 365 and 275 nm, resp. Release of the oxygen does not degrade the macrocyclic structure.

Three new sym. 9,10-dithienylanthracene (DTA) derivatives, including 9,10-bis-(4-(4-methoxyphenyl)-5-methylthiophene-2-yl)anthracene (BMPTA), 9,10-bis-(5-methyl-4-phenylthiophene-2-yl)anthracene (BPTA), and 9,10-bis-(4-(4-cyanophenyl)-5-methylthiophene-2-yl)anthracene (BCPTA), with excellent aggregation-induced emission (AIE) behaviors had been designed and synthesized successfully. Crystal BMPTA and BPTA had nonplanar conformations because of the multiple intermol. hydrogen bonding interaction between the adjacent mols., which restricted their intramol. rotation and enabled them to emit intensely. Addnl., both BMPTA and BPTA exhibited reversible mechanofluorochromic (MFC) performance by grinding-fuming, which was systematically investigated with powder X-ray diffraction (XRD), differential scanning calorimetry (DSC) and photoluminescent (PL) lifetime. The results showed that substituent groups had significant influence on their mol. packing, MFC and AIE properties. Furthermore, these DTA luminogens could be applied in cell imaging as fluorochrome.

Product Details of 523-27-3 The article mentions the following:

A family of mono- and dinuclear Ni(II) and Pd(II) complexes I, II, III and IV with a diverse and versatile α-diimine ligand environment for Suzuki-Miyaura cross-coupling (SMC) reactions was examined To evaluate the ligand steric effects, including the bite angle in the reaction outcomes, the structural variation of the complexes I, II, III and IV was achieved by incorporating iminopyridine- and acenaphthene-based ligands. Moreover, the impact of substrate bulkiness was investigated by reacting various aryl bromides RBr (R = Ph, 1H-indol-5-yl, 4-bromo-2,3,5,6-tetrafluorophenyl, etc.) with phenylboronic acid, 2-naphthylboronic acid, and 9-phenanthracenylboronic acid. Yields were the best with the dinuclear complex, being nearly quant. (93-99%), followed by the mononuclear complexes I and IV, giving yields of 78-98%. Consequently, α-diimine-based ligands V and VI have the potential to deliver Ni-based systems I and II as sustainable catalysts in SMC.

《Singlet oxygen stimulus for switchable functional organic cages》 was published in Chemical Science in 2020. These research results belong to Mongin, Cedric; Ardoy, Alejandro Mendez; Mereau, Raphael; Bassani, Dario M.; Bibal, Brigitte. Application In Synthesis of 9,10-Dibromoanthracene The article mentions the following:

Mol. cages 1a and 2a incorporating a 9,10-diphenylanthracene (DPA) chromophore were synthesized through a templated ring-closure metathesis approach that allows variation in cavity size through the introduction of up to three different pillars. Reversible Diels-Alder reaction between the DPA moiety and photogenerated singlet oxygen smoothly converted 1a and 2a to the corresponding endoperoxide cages 1b and 2b, which are converted back to 1a and 2a upon heating. Endoperoxide formation constitutes a reversible covalent signal that combines structural changes in the interior of the cage with introduction of two addnl. coordination sites. This results in a large modulation of the binding ability of the receptors attributed to a change in the location of the preferred binding site owing to the added coordination by the endoperoxide oxygen lone pairs. Cages 1a and 2a form complexes with sodium and cesium whose association constants are modified by 4-20 fold for Na+ and 200-450 fold for Cs+ upon conversion to 1b and 2b. DFT calculations show that in the anthracene form, cages 1a and 2a can bind 2 metal cations in their periphery so that each cation is coordinated by 4 oxygens and one amine nitrogen, whereas the endoperoxide cages 1b and 2b bind cations centrally in a geometry that favors coordination to the endoperoxide oxygens.9,10-Dibromoanthracene(cas: 523-27-3Application In Synthesis of 9,10-Dibromoanthracene) was used in this study.

Sun, Qing; Lu, Feng-Hui; Ni, Hong-Gang published an article in 2021. The article was titled 《Microplastic-water partitioning of two states halogenated PAHs: Solute and sol》, and you may find the article in Environmental Research.Formula: C14H8Br2 The information in the text is summarized as follows:

The complex interactions of contaminants with microplastics significantly affect ecol. risk assessments. Studies of the sorption behavior of freely dissolved hydrophobic organic contaminants (HOCs) on microplastics are common. However, concentrations of HOCs in the actual aquatic environment sometimes exceed their water solubility A possible explanation is that a microplastic-sol-water three-phase medium (TPM) is formed in the actual water environment. Both states HOCs (in solute and sol) have the potential to migrate to particles suspended in water. To confirm this view, four kinds of microplastics and eight halogenated polycyclic aromatic hydrocarbons (HPAHs) were selected to examine the partitioning of HPAHs between microplastics and water (sol and solute). Both monolayer and multilayer coverage of HPAHs onto microplastics occurred, and chem. sorption dominated the pseudo-sorption mechanism. The microplastic-water partition ratios of HPAHs (0.12-0.74) were approx. four to five orders of magnitude lower than their corresponding KOW values, suggesting that mechanisms other than sorption were involved. Apparently, the sol HPAHs contributed almost identically large increments to both microplastics and water, and closed the gap. For microplastic-supported HPAHs, the contribution of the sol fraction was more than triple that of the dissolved fraction; the key influencing factor was the water solubility of HPAHs. In the experiment, the researchers used 9,10-Dibromoanthracene(cas: 523-27-3Formula: C14H8Br2)
