Three coordination polymers (CPs) were synthesized by using CdII, fluorescent 9,10-di(4-pyridyl)anthracene (dpa), and cyclohexane-1,4-dicarboxylic acid (H2cda), and they are [Cd2(dpa)2(cda)Cl2]n (1), [Cd(dpa)2(cda)]n (2) and [Cd(dpa)(cda)(H2O)]n (3). Both 1 and 2 are fluorescent and contain nonporous layers. 3 is an isomer of 2 and contains a porous diamondoid network. Fluorescent mixed matrix membranes were prepared by dispersing the particles of 1 or 2 within the matrix of polymethyl methacrylate, and showed high sensitivity and selectivity for detecting Cr2O72- in water. Both stability and recyclability of the MMMs were remarkably higher than those of the CP powders.

Two bis-bis(urea) ligands (L1 and L2) incorporating the photoactive 9,10-diphenylanthracene fragment were designed for the construction of anion-coordination-driven assemblies and subsequent oxygenation of anthracene moieties for singlet oxygen storage. The corresponding A2L2-type sulfate complexes [TEA]4[(SO4)2(L1)2] (1) and [TEA]4[(SO4)2(L2)2] (2), where TEA = tetraethylammonium, were achieved by coordinating the ligands L1 or L2 with sulfate anions. Both 1 and 2 were able to undergo [4 + 2] photooxygenation to form endoperoxide photoproducts and , which can be partially converted back to the original anthracene compounds after heating. The structures of 1-EPO and 2-EPO were unambiguously confirmed by x-ray crystallog., NMR and UV-vis spectroscopy, and high-resolution electrospray ionization mass spectrometry.

Controlled generation of singlet oxygen is very important due to its involvement in scheduled cellular maintenance processes and therapeutic potential. As a consequence, precise manipulation of singlet oxygen release rates under mild conditions, is crucial. In this work, a cross-linked polyacrylate, and a polydimethylsiloxane elastomer incorporating anthracene-endoperoxide modules with chain extensions at the 9,10-positions were synthesized. We now report that on mech. agitation in cryogenic ball mill, fluorescence emission due to anthracene units in the PMA (polymethacrylate) polymer is enhanced, with a concomitant generation of singlet oxygen as proved by detection with a selective probe. The PDMS (polydimethylsiloxane) elastomer with the anthracene endoperoxide mechanophore, is also similarly sensitive to mech. force.

Han, Yanning; Zhang, Tong; Chen, Qiao; Chen, Xinyu; Xue, Pengchong published an article in 2021. The article was titled 《π-Stacking Conversion and Enhanced Force-Stimuli Response of a Divinylanthracene Derivative in a Hydrogen-Bonded Framework》, and you may find the article in Crystal Growth & Design.Related Products of 523-27-3 The information in the text is summarized as follows:

Hydrogen bond-induced π-stacking conversion was used to achieve an enhanced force-stimuli response of 9,10-bis(2-(pyridin-4-yl)vinyl)anthracene (BP4VA). In BP4VA crystals, the mols. adopted a J-aggregate pattern, and no overlap between the central anthracene planes was observed Trimesic acid (TA) as a hydrogen bond donor could promote the transformation of the π-stacking type of BP4VA as a hydrogen bond acceptor. It was found that TA and BP4VA mols. formed two-dimensional lamellar hydrogen-bonded frameworks with large windows, which were filled by BP4VA mols. belonging to other layers. Within such three-dimensional packing, J-aggregate stacking type of BP4VA converted into a mixture of J-type and H-type dimers. Moreover, BP4VA adopted a highly twisted conformation, and π-π interaction between them was very weak. So, the hydrogen-bonded complex emitted a short wavelength fluorescence. More importantly, the yellow hydrogen-bonded complex turned into red solids under force stimuli, and its fluorescence had a fairly large shift of more than 110 nm. This is in contrast with a spectral shift of 43 nm from the sheared neat BP4VA crystals. Quantum chem. calculation and spectral observations implied that the planarization, shortened π-distance, and large overlap between anthracene units should be responsible for the large spectral shift. The results imply that the appropriate acid as a hydrogen bond donor might help distyrylanthracene derivatives possess outstanding functions.

《Determining sub-cooled liquid vapor pressures and octanol-air partition coefficients for chlorinated and brominated polycyclic aromatic hydrocarbons based on gas chromatographic retention times: Application for gas/particle partitioning in air》 was written by Vuong, Quang Tran; Thang, Phan Quang; Ohura, Takeshi; Choi, Sung-Deuk. SDS of cas: 523-27-3This research focused onvapor pressure octanol air partition coefficient PAH GCRT partitioning. The article conveys some information:

Halogenated polycyclic aromatic hydrocarbons (Halo-PAHs) are a new group of PAH derivatives and are reported to be more toxic than their parent PAHs. However, limited research has been undertaken on their physicochem. properties. In this study, subcooled liquid vapor pressures (PL) and octanol-air partition coefficients (KOA) of 24 chlorinated and 11 brominated PAHs (ClPAHs and BrPAHs) were determined using the gas chromatog. retention time (GC-RT) technique. The temperature dependences of PL and KOA for the Halo-PAHs were determined by the slopes and intercepts of the linear regressions. The GC-RT method also provided the enthalpies of vaporization (ΔHL) and internal energies of phase transfer (ΔUOA) for all interested compounds The activity of Halo-PAHs in octanol (γoct) ranging from 18 to 87, indicated the non-ideal solution behavior. The number of the chlorine atoms in the PAH rings could influence the interaction of ClPAHs with the organic matter, whereas this interaction for BrPAHs could not be studied due to the limited number of target BrPAHs. The measured values of PL and KOA were applied to investigate the gas/particle partition behaviors of Halo-PAHs in Ulsan, South Korea. This study is so far the first one to report the linear regression coefficients, which can be used to estimate the PL and KOA values of Halo-PAHs at any temperature The experimental part of the paper was very detailed, including the reaction process of 9,10-Dibromoanthracene(cas: 523-27-3SDS of cas: 523-27-3)

Hong, Haitao; Wu, Ni; Han, Mingxi; Guo, Zhiyong; Zhan, Hongbing; Du, Shaowu; Chen, Banglin published their research in Materials Chemistry Frontiers in 2021. The article was titled 《An anthracene based conjugated triazine framework as a luminescent probe for selective sensing of p-nitroaniline and Fe(III) ions》.SDS of cas: 523-27-3 The article contains the following contents:

Covalent triazine frameworks (CTFs), as a burgeoning type of porous organic material, have attracted increasing attention in a lot of research fields, including gas separation, heterogeneous catalysis, etc. In particular, stemming from their heteroatom effect (HAE), incorporated with the merits of π-conjugated frameworks, electron-rich triazine units and extraordinary chem. stability, they exhibit prospective potential applications in chem. sensing. In this paper, a triazine-based conjugated porous organic polymer (DPA-CTF) containing anthracene units was used to study the sensing effects on nitroarom. compounds and metal ions. Intriguingly, DPA-CTF showed sensitive detection performance towards nitroarom. explosives, especially p-nitroaniline (p-NA). Besides, it also exhibited high sensitivity toward Fe3+ ions compared to other metal ions. A series of characterization studies and computational simulations were used to explain the mechanism of the luminescence quenching effect. These results manifest that the new synthesized CTF is a promising candidate as a chem. sensor for p-NA and Fe3+ ions. In addition to this study using 9,10-Dibromoanthracene, there are many other studies that have used 9,10-Dibromoanthracene(cas: 523-27-3SDS of cas: 523-27-3) was used in this study.
