Quality Control of 9,10-Dibromoanthracene And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Mol. assembly is crucial in functional mol. materials and devices. Among the mol. interactions that can form assemblies, stacking among π-conjugated mol. backbones plays an essential role in charge transport through organic materials and devices. The single-mol. junction technique allows for the application of an elec. field of approx. 108 V/m to the nanoscale junctions and to investigate the elec. field-induced assembly at the single-stacking level. Here, we demonstrate an elec. field-induced stacking effect between two mols. using the scanning tunneling microscope break junction (STM-BJ) technique and we found an increase in the stacking probability with increasing intensity of the elec. field. The combined d. functional theory (DFT) calculations suggest that the mols. become more planar under the elec. field, leading to the energetically preferred stacking configuration. Our study provides a new strategy for tuning mol. assembly by employing a strong elec. field. The experimental part of the paper was very detailed, including the reaction process of 9,10-Dibromoanthracene(cas: 523-27-3Quality Control of 9,10-Dibromoanthracene)

《Anisotropic Poisson Effect and Deformation-Induced Fluorescence Change of Elastic 9,10-Dibromoanthracene Single Crystals》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Hayashi, Shotaro; Ishiwari, Fumitaka; Fukushima, Takanori; Mikage, Shohei; Imamura, Yutaka; Tashiro, Motomichi; Katouda, Michio. Application of 523-27-3 The article mentions the following:

Elastic organic crystals have attracted considerable attention as next-generation flexible smart materials. However, the detailed information on both mol. packing change and macroscopic mech. crystal deformations upon applied stress is still insufficient. Herein, we report that fluorescent single crystals of 9,10-dibromoanthracene are elastically bendable and stretchable, which allows a detailed investigation of the deformation behavior. We clearly observed a Poisson effect for the crystal, where the short axes (b and c-axes) of the crystal are contracted upon elongation along the long axis (a-axis). Moreover, we found that the Poisson’s ratios along the b-axis and c-axis are largely different. Theor. mol. simulation suggests that the tilting motion of the anthracene may be responsible for the large deformation along the c-axis. Spatially resolved photoluminescence (PL) measurement of the bent elastic crystals reveals that the PL spectra at the outer (elongated), central (neutral), and inner (contracted) sides are different from each other.

McCurdy, Ryan D.; Jacobse, Peter H.; Piskun, Ilya; Veber, Gregory C.; Rizzo, Daniel J.; Zuzak, Rafal; Mutlu, Zafer; Bokor, Jeffrey; Crommie, Michael F.; Fischer, Felix R. published an article in 2021. The article was titled 《Synergetic Bottom-Up Synthesis of Graphene Nanoribbons by Matrix-Assisted Direct Transfer》, and you may find the article in Journal of the American Chemical Society.Product Details of 523-27-3 The information in the text is summarized as follows:

The scope of graphene nanoribbon (GNR) structures accessible through bottom-up approaches is defined by the intrinsic limitations of either all-on-surface or all-solution-based synthesis. Here, we report a hybrid bottom-up synthesis of GNRs based on a Matrix-Assisted Direct (MAD) transfer technique that successfully leverages tech. advantages inherent to both solution-based and on-surface synthesis while sidestepping their drawbacks. Critical structural parameters tightly controlled in solution-based polymerization reactions can seamlessly be translated into the structure of the corresponding GNRs. The transformative potential of the synergetic bottom-up approaches facilitated by the MAD transfer techniques is highlighted by the synthesis of chevron-type GNRs (cGNRs) featuring narrow length distributions and a nitrogen core-doped armchair GNR (N4-7-ANGR) that remains inaccessible using either a solution-based or an on-surface bottom-up approach alone.

The article was titled 《Halogenated polycyclic aromatic hydrocarbons in edible aquatic species of two Asian countries: Congener profiles, biomagnification, and human risk assessment》.Application In Synthesis of 9,10-Dibromoanthracene The article contains the following contents:

Seventy-five contaminants including chlorinated/brominated/parent polycyclic aromatic hydrocarbons (Cl/Br/PAHs) were investigated in 29 edible aquatic species from the Indian Ocean near Sri Lanka and 10 species from the Pacific Ocean near Japan. Concentrations of total ClPAHs and BrPAHs in the samples were 2.6-57 and 0.30-9.5 ng/g-dry weight from the Indian Ocean, and 0.35-18 and 0.03-3.3 ng/g-dry weight from the Pacific Ocean, resp. Comparing the profiles of Cl/BrPAHs among the samples, congeners of chlorinated and brominated pyrene were predominant components and enhanced the potential for biomagnification in the sample from the off-shore pelagic environment in the Indian Ocean. The incremental lifetime cancer risks estimated by intake of the targets in consuming aquatic organisms showed that approx. one-third of studied organisms exceeded the acceptable risk level for Sri Lankans.

The article was titled 《Ultrastable luminescent hybrid microporous polymers based on polyhedral oligomeric silsesquioxane for CO2 uptake and metal ion sensing》, and you may find the article in Microporous and Mesoporous Materials.Safety of 9,10-Dibromoanthracene The information in the text is summarized as follows:

In this study we prepared four different fluorescent hybrid microporous polymers (HPPs) derived from cubic octavinylsilsesquioxane (OVS) through Heck coupling with brominated anthracene (An-Br2), triphenyltriazine (TPT-Br3), bicarbazole (Car-Br4) and tetraphenylethene (TPE-Br4). The chem. structures of these HPPs were confirmed using Fourier transform IR spectroscopy and solid-state NMR spectroscopy. Thermogravimetric anal. and N2 adsorption/desorption measurements revealed that each of these HPPs had outstanding thermal stability, a high surface area, and inherent porosity. The CO2 uptakes of TPT-HPP and Car-HPP at 273 and 298 K were higher than those of An-HPP and TPE-HPP. Furthermore, the luminescence of these HPPs could be quenched completely upon the addition of Fe2+, and Fe3+ metal cations. Thus, these HPP materials appear to be good candidates for CO2 adsorption and metal ion sensing.

Category: bromides-buliding-blocksIn 2021 ,《Three-State Switching of an Anthracene Extended Bis-thiaxanthylidene with a Highly Stable Diradical State》 was published in Journal of the American Chemical Society. The article was written by Wonink, Marco B. S.; Corbet, Brian P.; Kulago, Artem A.; Boursalian, Gregory B.; de Bruin, Bas; Otten, Edwin; Browne, Wesley R.; Feringa, Ben L.. The article contains the following contents:

A multistable mol. switching system based on an anthracene-extended bis-thiaxanthylidene with three individually addressable states that can be interconverted by electrochem., thermal, and photochem. reactions is reported. Besides reversible switching between an open-shell diradical- and a closed-shell electronic configuration, our findings include a third dicationic state and control by multiple actuators. This dicationic state with an orthogonal conformation can be switched electrochem. with the neutral open-shell triplet state with orthogonal conformation, which was characterized by EPR. The remarkably stable diradical shows kinetic stability as a result of a significant activation barrier for isomerization to a more stable neutral closed-shell folded geometry. We ascribe this activation barrier of ΔG(293 K) = 25.7 kcal mol-1 to steric hindrance in the fjord region of the overcrowded alkene structure. The folded closed-shell state can be converted back to the diradical state by irradiation with 385 nm. The folded state can also be oxidized to the dicationic state. These types of mols. with multiple switchable states and in particular stable diradicals show great potential in the design of new functional materials such as memory devices, logic gates, and OFETs. In the experiment, the researchers used many compounds, for example, 9,10-Dibromoanthracene(cas: 523-27-3Category: bromides-buliding-blocks)
