《Synthesis and Cross-Linking of a Benzoxazine-Containing Anthracene Moiety: Thermally Stable Photoluminescent Benzoxazine Resin》 was published in Macromolecules (Washington, DC, United States) in 2020. These research results belong to Goto, Masahide; Yajima, Tatsuo; Minami, Masaki; Sogawa, Hiromitsu; Sanda, Fumio. SDS of cas: 523-27-3 The article mentions the following:

A novel benzoxazine derivative, 9,10-bis(6-ethynyl-3-phenyl-3,4-dihydro-1,3-benzoxazine)anthracene (1a), was synthesized by the Sonogashira-Hagihara coupling reaction of 9,10-dibromoanthracene and 6-ethynyl-3-phenyl-3,4-dihydro-1,3-benzoxazine. A CH2Cl2 solution of 1a luminesced with a high quantum yield (Φ = 81%). Compound 1a afforded solvent-insoluble cross-linked polybenzoxazine 1b by the bulk polymerization at 250°C. Solution polymerization of a dilute solution of 1a at 200°C afforded solvent-soluble samples, accompanied by a decrease of photoluminescence intensity. The weight loss values of 1a and 1b were 81 and 87%, resp., under nitrogen at 500°C. We believe that the present study will lead to thermally stable curing resins whose degree of curing can be estimated with the naked eye by observing the decrease of photoluminescence. In the experiment, the researchers used many compounds, for example, 9,10-Dibromoanthracene(cas: 523-27-3SDS of cas: 523-27-3)

9,10-Dibromoanthracene(cas: 523-27-3) is synthesized by the bromination of anthracene. The bromination reaction is carried out at room temperature using carbon tetrachloride as a solvent. Using 80-85% anthracene as raw material, adding bromine to react for half an hour, the yield is 83-88%.SDS of cas: 523-27-3

Teresa published their research in Angewandte Chemie, International Edition in 2021. The article was titled 《Single-Molecule Conductance of 1,4-Azaborine Derivatives as Models of BN-doped PAHs》.Name: 9,10-Dibromoanthracene The article contains the following contents:

The single-mol. conductance of a series of BN-acene-like derivatives has been measured by using scanning tunneling break-junction techniques. A strategic design of the target mols. has allowed us to include azaborine units in positions that unambiguously ensure electron transport through both heteroatoms, which is relevant for the development of customized BN-doped nanographenes. We show that the conductance of the anthracene azaborine derivative is comparable to that of the pristine all-carbon anthracene compound Notably, this heteroatom substitution has also allowed us to perform similar measurements on the corresponding pentacene-like compound, which is found to have a similar conductance, thus evidencing that B-N doping could also be used to stabilize and characterize larger acenes for mol. electronics applications. Our conclusions are supported by state-of-the-art transport calculations In the part of experimental materials, we found many familiar compounds, such as 9,10-Dibromoanthracene(cas: 523-27-3Name: 9,10-Dibromoanthracene)

《Seasonal variation and gas/particle partitioning of atmospheric halogenated polycyclic aromatic hydrocarbons and the effects of meteorological conditions in Ulsan, South Korea》 was written by Vuong, Quang Tran; Thang, Phan Quang; Nguyen, Tuyet Nam Thi; Ohura, Takeshi; Choi, Sung-Deuk. Recommanded Product: 523-27-3 And the article was included in Environmental Pollution (Oxford, United Kingdom) in 2020. The article conveys some information:

Atm. halogenated polycyclic aromatic hydrocarbons (Halo-PAHs) and parent PAHs were monitored in Ulsan, South Korea for one year (Jan.-Dec. 2015) to investigate their seasonal patterns, gas/particle partitioning behavior, and the impact of meteorol. conditions. The mean concentrations of 24 chlorinated PAHs, 11 brominated PAHs, and 13 parent PAHs in the gaseous and particulate phases were 8.64 and 9.64 pg/m3, 11.6 and 1.62 pg/m3, and 2.17 and 2.40 ng/m3, resp. Winter had the highest ClPAH and PAH levels, with significant contributions from poly-chlorine groups and high-mol.-weight compounds However, BrPAHs showed reverse patterns with the highest concentration in summer and the dominant gaseous fraction throughout the year. In contrast, the effects of the temperature inversion layer and atm. transport from the outside of Ulsan were more apparent for ClPAHs and PAHs, particularly in winter and spring. Regarding gas/particle partitioning, Halo-PAHs exhibited different seasonal behaviors from those of parent PAHs. This study implies that Halo-PAHs and parent PAHs might not share the same atm. behavior, possibly due to different characteristics in atm. reactions with other chems. and particle-size distribution. However, there have been limited studies about the formation of Halo-PAHs and their physicochem. properties; hence, further in-depth investigations are of vital importance. In the experiment, the researchers used 9,10-Dibromoanthracene(cas: 523-27-3Recommanded Product: 523-27-3)

The title of the article was 《Ultrastable Covalent Triazine Organic Framework Based on Anthracene Moiety as Platform for High-Performance Carbon Dioxide Adsorption and Supercapacitors》.Application In Synthesis of 9,10-Dibromoanthracene The author mentioned the following in the article:

Conductive and porous nitrogen-rich materials have great potential as supercapacitor electrode materials. The exceptional efficiency of such compounds, however, is dependent on their larger surface area and the level of nitrogen doping. To address these issues, we synthesized a porous covalent triazine framework (An-CTFs) based on 9,10-dicyanoanthracene (An-CN) units through an ionothermal reaction in the presence of different molar ratios of molten zinc chloride (ZnCl2) at 400 and 500 °C, yielding An-CTF-10-400, An-CTF-20-400, An-CTF-10-500, and An-CTF-20-500 microporous materials. According to N2 adsorption-desorption analyses (BET), these An-CTFs produced exceptionally high sp. surface areas ranging from 406-751 m2·g-1. Furthermore, An-CTF-10-500 had a capacitance of 589 F·g-1, remarkable cycle stability up to 5000 cycles, up to 95% capacity retention, and strong CO2 adsorption capacity up to 5.65 mmol·g-1 at 273 K. As a result, our An-CTFs are a good alternative for both electrochem. energy storage and CO2 uptake.

《Cooperativity within the catalyst: alkoxyamide as a catalyst for bromocyclization and bromination of (hetero)aromatics》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Mondal, Haripriyo; Sk, Raja Md; Maji, Modhu Sudan. Computed Properties of C14H8Br2 The article mentions the following:

N-Methoxy-1-butanesulfonamide was a recyclable catalyst for the activation of N-bromosuccinimide to perform bromocyclization and bromination reactions of unsaturated carboxylic acids, alkenes and indoles with pendant nucleophiles, and arenes in heptane, where adequate suppression of the background reactions was observed, to yield bromolactones, bromomethyl-substituted heterocycles, fused indolines such as pyrroloindolines, and aryl bromides. The key feature of the active site is the alkoxy group attached to the sulfonamide moiety, which facilitates the acceptance as well as the delivery of bromonium species from the bromine source to the substrates.

Teresa; Agraeit, Nicolas; Zotti, Linda A.; Esser, Birgit; Leary, Edmund published their research in Chemical Communications (Cambridge, United Kingdom) in 2021. The article was titled 《Single-molecule conductance of dibenzopentalenes: antiaromaticity and quantum interference》.HPLC of Formula: 523-27-3 The article contains the following contents:

The effects of antiaromaticity and destructive quantum interference (DQI) are investigated on the charge transport through dibenzo-[a,e]pentalene (DBP). 5,10-Connectivity gives high single-mol. conductance whereas 2,7 gives low conductance due to DQI. Comparison of the 5,10-DBP with Ph and anthracene analogs yields the trend GDBP ≈ GAnth > GPh, despite the aromatic anthracene having a larger HOMO-LUMO gap than 5,10-DBP. This is explained by unfavorable level alignment for 5,10-DBP. After reading the article, we found that the author used 9,10-Dibromoanthracene(cas: 523-27-3HPLC of Formula: 523-27-3)

In 2022,Asfandiarov, N. L.; Muftakhov, M. V.; Rakhmeev, R. G.; Safronov, A. M.; Markova, A. V.; Pshenichnyuk, S. A. published an article in Journal of Electron Spectroscopy and Related Phenomena. The title of the article was 《Non covalent bonds in some bromo-substituted aromatic anions》.Name: 9,10-Dibromoanthracene The author mentioned the following in the article:

Four bromo-substituted derivatives of naphthalene and anthracene were studied by means of Dissociative Electron Attachment Spectroscopy. Long-lived mol. anions with lifetimes ranging from 25 to 144μs were observed in all mols. under investigation. In all cases mol. anion fragmentation is poor: only the Br- , [M-Br]- and (with very small intensity) [M-H]- species were observed, except for the case of 9,10-Br2-anthracene. It was shown that the presence of long-lived mol. anions in 1-Br- and 2-Br-naphthalene (τa = 26μs and τa = 25μs, resp.) does not contradict the fact that their dissociation rates measured by the pulse radiolysis method are fairly large (1.0 x1010 s-1 and 1.8 x1010 s-1, resp.). Scanning the potential energy surface of anions in the process of positioning a bromine anion around a polarized aromatic radical revealed the presence of a series of local min. separated by potential barriers. It is inferred that the most energetically favorable structures of the 1-Br- and 2-Br-naphthalene anions should be interpreted as complexes of the bromide anion bound to the polarized aromatic radical by non-covalent Br-H bonds. Similar local min. were found in the 9-Br- and 9,10-Br2-anthracene anions, but the energies of these structures are significantly higher than those of the “”standard”” anionic structures with a C-Br bond length of ∼1.93 Å. The EAas obtained with DFT CAM-B3LYP/6-311 +G(d,p) calculations are in acceptable agreement with the estimates made within the framework of the simple Arrhenius model from the lifetimes of mol. anions. In the experiment, the researchers used many compounds, for example, 9,10-Dibromoanthracene(cas: 523-27-3Name: 9,10-Dibromoanthracene)
