Triplet-triplet annihilation (TTA) upconversion is a special non-linear photophys. process that converts low-energy photons into high-energy photons based on sensitizer/annihilator pairs. Here, we constructed a novel luminescence ratiometric nanothermometer based on TTA upconversion nanomicelles by encapsulating sensitizer/annihilator mols. into a temperature-sensitive amphiphilic triblock polymer and obtained good linear relationships between the luminescence ratio (integrated intensity ratio of upconverted luminescence peak to the downshifted phosphorescence peak) and the temperature We also found chem. modification of annihilators would rule out the interference of the polymer concentration and stereochem. engineering of annihilators would readily regulate the thermal sensitivity. In addition to this study using 9,10-Dibromoanthracene, there are many other studies that have used 9,10-Dibromoanthracene(cas: 523-27-3Quality Control of 9,10-Dibromoanthracene) was used in this study.

Synthetic Route of C14H8Br2In 2020 ,《Switchable Conformational Isomerization of an Overcrowded Tristricyclic Aromatic Ene》 was published in Journal of Organic Chemistry. The article was written by Nishiuchi, Tomohiko; Ito, Ryuoh; Stratmann, Erik; Kubo, Takashi. The article contains the following contents:

We have prepared a new overcrowded tristricyclic aromatic ene (TAE) and investigated its external stimuli-responsive behavior for the interconversion between a closed-shell folded form and an open-shell twisted form. Upon photoirradiation, the folded form transforms into the biradical twisted form, whereas by keeping the twisted form in the dark, the reverse reaction gradually occurs at room temperature This switchable conformational change is analyzed by means of UV-Vis and ESR spectroscopies, cyclic voltammetry, d. functional theory (DFT) calculations, and kinetic studies.

In 2022,Xu, Kaidi; Li, Bin; Yao, Shibo; Li, Zhaoxian; Lu, Yunfeng; Dong, Ming; Qiu, Jianfeng; Luo, Liqiang; Li, Chunju published an article in Angewandte Chemie, International Edition. The title of the article was 《Modular Introduction of endo-Binding Sites in a Macrocyclic Cavity towards Selective Recognition of Neutral Azacycles》.Electric Literature of C14H8Br2 The author mentioned the following in the article:

Macrocycles with a functionalized interior, which is a general cavity feature of bioreceptors, are relatively hard to synthesize. Here authors report a modular strategy to customize diverse endo-binding sites in the macrocycle cavity. Only two steps are needed. First, one V-shaped functional module bearing an embedded binding site and two 2,5-dimethoxyphenyls as reaction modules are connected. Then the condensation of the resulting monomer and paraformaldehyde directly produces the designed macrocycle. V-shaped monomers are deliberately used to guarantee the binding sites equatorially directing inward into the cavity and 2,5-dimethoxyphenyls standing axially as macrocycle sidewalls. More than a dozen endo-functionalized macrocyclic receptors have been constructed. Host-guest complexation studies show that interior OH moieties in macrocycle I can strongly encapsulate neutral azacycles by forming inner hydrogen bonds, giving a high association constant of 4.59×104 M-1 in non-polar media. The results came from multiple reactions, including the reaction of 9,10-Dibromoanthracene(cas: 523-27-3Electric Literature of C14H8Br2)

In 2022,Kashino, Tsubasa; Haruki, Rena; Uji, Masanori; Harada, Naoyuki; Hosoyamada, Masanori; Yanai, Nobuhiro; Kimizuka, Nobuo published an article in ACS Applied Materials & Interfaces. The title of the article was 《Design Guidelines for Rigid Epoxy Resins with High Photon Upconversion Efficiency: Critical Role of Emitter Concentration》.Related Products of 523-27-3 The author mentioned the following in the article:

For the practical application of triplet-triplet annihilation-based photon upconversion (TTA-UC), the development of rigid, transparent, air-stable, and moldable materials with a high TTA-UC efficiency remains a challenging issue. In addition to the noncovalent introduction of ionic liquid emitters into the epoxy network, we covalently introduce emitters with polymerization sites to increase the emitter concentration to 35.6 wt %. A TTA-UC quantum yield ΦUC of 5.7% (theor. maximum: 50%) or a TTA-UC efficiency ηUC of 11.4% (theor. maximum: 100%) is achieved, which is the highest value ever achieved for a rigid polymer material. More importantly, the high emitter concentration speeds up the triplet diffusion and suppresses the back energy transfer from the emitter to sensitizer so that the sensitized emitter triplet can be effectively utilized for TTA. The generality of our finding is also confirmed for epoxy resins of similar emitter unit concentrations without the ionic liquid This work provides important design guidelines for achieving highly efficient TTA-UC in rigid solid materials, which has been very difficult to achieve in the past. Furthermore, the solid-state TTA-UC exhibits high air stability, reflecting the high oxygen barrier performance of epoxy resins. The high moldability of epoxy resins allows the construction of upconversion materials with complex geometries at nano- to macroscopic scales. In the part of experimental materials, we found many familiar compounds, such as 9,10-Dibromoanthracene(cas: 523-27-3Related Products of 523-27-3)

Synthetic Route of C14H8Br2In 2020 ,《Edge-On Self-Assembly of Tetra-bromoanthracenyl-porphyrin on Silver Surfaces》 was published in Journal of Physical Chemistry C. The article was written by Kalashnyk, Nataliya; Daher Mansour, Michel; Pijeat, Joffrey; Plamont, Remi; Bouju, Xavier; Balaban, Teodor Silviu; Campidelli, Stephane; Masson, Laurence; Clair, Sylvain. The article contains the following contents:

Mol. self-assembly on surfaces is driven by the range of interactions between the mols. themselves and the substrate. Generally, a face-on structure is favored for aromatic mols. lying flat on the surface. Here, the authors report on the supramol. self-assembly of 5,10,15,20-tetrakis(10-bromoanthracen-9-yl)porphyrin on the Ag(111) and Ag(110) surfaces. Well-ordered mol. chains were observed by room-temperature scanning tunneling microscopy on both surfaces. The relatively small size of the unit cell revealed an edge-on configuration of the porphyrin macrocycles, i.e., perpendicular to the surface plane, as confirmed by mol. mechanics calculations Distinct intermol. interactions were found on the 2 surfaces, providing different mol. chain orientations on Ag(111) and Ag(110).

Application In Synthesis of 9,10-DibromoanthraceneIn 2021 ,《Tackling Solubility Issues in Organic Synthesis: Solid-State Cross-Coupling of Insoluble Aryl Halides》 was published in Journal of the American Chemical Society. The article was written by Seo, Tamae; Toyoshima, Naoki; Kubota, Koji; Ito, Hajime. The article contains the following contents:

Conventional organic synthesis generally relies on the use of liquid organic solvents to dissolve the reactants. Therefore, reactions of sparingly soluble or insoluble substrates are challenging and often ineffective. The development of a solvent-independent solid-state approach that overcomes this longstanding solubility issue would provide innovative synthetic solutions and access to new areas of chem. space. Here, we report extremely fast and highly efficient solid-state palladium-catalyzed Suzuki-Miyaura cross-coupling reactions via a high-temperature ball-milling technique. This solid-state protocol enables the highly efficient cross-couplings of insoluble aryl halides with large polyaromatic structures that are barely reactive under conventional solution-based conditions. Notably, we discovered a new luminescent organic material with a strong red emission. This material was prepared via the solid-state coupling of Pigment violet 23, a compound that has so far not been involved in mol. transformations due to its extremely low solubility This study thus provides a practical method for accessing unexplored areas of chem. space through mol. transformations of insoluble organic compounds that cannot be carried out by any other approach.

《Scale-Up of Room-Temperature Constructive Quantum Interference from Single Molecules to Self-Assembled Molecular-Electronic Films》 was published in Journal of the American Chemical Society in 2020. These research results belong to Wang, Xintai; Bennett, Troy L. R.; Ismael, Ali; Wilkinson, Luke A.; Hamill, Joseph; White, Andrew J. P.; Grace, Iain M.; Kolosov, Oleg V.; Albrecht, Tim; Robinson, Benjamin J.; Long, Nicholas J.; Cohen, Lesley F.; Lambert, Colin J.. HPLC of Formula: 523-27-3 The article mentions the following:

The realization of self-assembled mol.-electronic films, whose room-temperature transport properties are controlled by quantum interference (QI), is an essential step in the scale-up of QI effects from single mols. to parallel arrays of mols. Recently, the effect of destructive QI (DQI) on the elec. conductance of self-assembled monolayers (SAMs) has been investigated. Here, through a combined exptl. and theor. investigation, we demonstrate chem. control of different forms of constructive QI (CQI) in cross-plane transport through SAMs and assess its influence on cross-plane thermoelectricity in SAMs. It is known that the elec. conductance of single mols. can be controlled in a deterministic manner, by chem. varying their connectivity to external electrodes. Here, by employing synthetic methodologies to vary the connectivity of terminal anchor groups around aromatic anthracene cores, and by forming SAMs of the resulting mols., we clearly demonstrate that this signature of CQI can be translated into SAM-on-gold mol. films. We show that the conductance of vertical mol. junctions formed from anthracene-based mols. with two different connectivities differ by a factor of approx. 16, in agreement with theor. predictions for their conductance ratio based on CQI effects within the core. We also demonstrate that for mols. with thioether anchor groups, the Seebeck coefficient of such films is connectivity dependent and with an appropriate choice of connectivity can be boosted by ~50%. This demonstration of QI and its influence on thermoelectricity in SAMs represents a critical step toward functional ultra-thin-film devices for future thermoelec. and mol.-scale electronics applications.

Liu, Naifang; Chen, Zhihui; Fan, Wenxuan; Su, Jie; Lin, Tingting; Xiao, Si; Meng, Jianqiao; He, Jun; Vittal, Jagadese J.; Jiang, Jianzhuang published an article in 2022. The article was titled 《Highly Efficient Multiphoton Absorption of Zinc-AIEgen Metal-Organic Frameworks》, and you may find the article in Angewandte Chemie, International Edition.Product Details of 523-27-3 The information in the text is summarized as follows:

A series of luminescent frameworks was synthesized from the selective combination of aggregation induced emission (AIE)-linker tetra-(4-carboxylphenyl)ethylene (H4TCPE) and Zn2+. Complex 1 was formed by the close packing of Zn-TCPE hinge, and isostructural complexes 2-5 were constructed by the linkage of Zn-TCPE layer and pillar ligands. These complexes exhibit highly efficient multiphoton excited photoluminescence (MEPL) and concomitant third-harmonic generation (THG). The multiphoton absorption (MPA) parameters of 1 are superior to other multiphoton emission materials including the perovskite nanocrystals. The incorporation of pillar linkers slows down the charge transfer between layers of Zn-TCPE, and the aromatic core of pillar linkers has a great influence on the MPA performance of the corresponding frameworks.
