Ju, Cheng-Wei;Li, Bo;Li, Lianghui;Yan, Weiguang;Cui, Chunming;Ma, Xiaonan;Zhao, Dongbing research published 《 Modular Synthesis of Pentagonal and Hexagonal Ring-Fused NBN-Phenalenes Leading to an Excited-State Aromatization-Induced Structural Planarization Molecular Library》, the research content is summarized as follows. Although polycyclic aromatic hydrocarbons (PAHs) with a nitrogen-boron-nitrogen (NBN) moiety have recently attracted tremendous interest due to their intriguing electronic and optoelectronic properties, all of the NBN-fused π-systems reported to date are called NBN-dibenzophenalenes and were synthesized by electrophilic aromatic substitution. The synthesis of NBN-phenalenes remains challenging, and transition-metal catalysis has never been utilized to construct NBN-embedded π-scaffolds. Herein, a palladium-catalyzed cyclization/bicyclization strategy was developed for the synthesis of diverse pentagonal and hexagonal ring-fused NBN-phenalenes and half-NBN-phenalenes. All of the NBN-embedded π-scaffolds presented in our paper are fluorescent in both solution and the solid state. Further investigations showed that the five-membered NBN rings exhibit the properties of traditional luminogens, while those with a six-membered NBN ring generally undergo photoinduced structural planarization (PISP) and exhibit different colors and quantum yields of fluorescence with different concentrations in solution Time-resolved spectroscopy and TD-DFT calculations revealed that excited-state aromatization is the driving force for PISP in hexagonal ring-fused NBN-π systems, leading to the formation of excimers. Notably, the scope of PISP compounds is still quite limited, and PISP has never been observed in NBN-π systems before. These hexagonal ring-fused NBN-π systems constitute a novel PISP mol. library and appear to be a new class of aggregation-induced excimer emission (AIEE) materials. Finally, the AIEE behavior of these six-membered NBN rings was applied to the detection of nitro explosives, achieving excellent sensitivity. In general, this work provides a new viewpoint for synthesizing NBN-fused π-systems and understanding the excited-state motion of luminogens.

1-Bromo-3,5-dimethoxybenzene (1BDMB) is a synthetic molecule that can be used as an electron acceptor in organic photovoltaic cells. 1BDMB is a salt of the sodium salt of resorcylic acid and 1,3-dibromo-5,5-dimethoxybenzene. It has been shown to have a radical mechanism for the generation of free radicals. The radical mechanism is initiated by light absorption by the ruthenium complex at the center of the molecule which induces photoinduced electron transfer from the ruthenium to 1BDMB. This process results in electron transfer from the donor to an acceptor molecule, such as oxygen or nitrogen. The pharmacokinetic properties of this compound are not well known; however, it has been demonstrated that it can be synthesized through a cross-coupling reaction with other aromatic compounds such as stemofuran., 20469-65-2.

Kadafour, Attahir N. W.;Bala, Muhammad D. research published 《 Structural characterization of a square planar Ni(II) complex and its application as a catalyst for the transfer hydrogenation of ketones》, the research content is summarized as follows. A new 2-hydroxy-1-naphthaldehyde Schiff base derived nickel(II) complex (4) was synthesized and fully characterized. Anal. of the structure of 4 by single-crystal X-ray diffraction shows two chelating Schiff base ligands bound to nickel in a trans [O^ΛN(Ni²⁺)N^ΛO] fashion. Hence, in a mol. of 4, two ligands are four coordinate to a Ni(II) center through the imine nitrogen and naphthyloxyl oxygen atoms. This coordination mode resulted in a square planar complex that is stabilized in the solid-state by a network of intermol. O-H···N hydrogen bonds between neighboring mols. The ¹H NMR data showed the loss of the hydroxyl (OH) proton signal and an upfield shift of the metal-bound imine (-NH) proton signal, while the IR data also showed a lower energy shift in the absorption frequency of the imine (C = N) bond due to back donation from the coordinated Ni(II) center. As a catalyst for the transfer hydrogenation of a range of ketones, 4 showed good catalytic activity at a very low concentration of 0.1 mol% with 2-propanol as the model substrate. The catalyst is also effective for various related ketone substrates bearing a range of steric and electronic regulating groups.

Through a phenotypic high-throughput screen using a serum response element luciferase promoter, we identified a novel 5-aryl-1,3,4-oxadiazol-2-ylthiopropionic acid lead inhibitor of Rho/myocardin-related transcription factor (MRTF)/serum response factor (SRF)-mediated gene transcription with good potency (IC₅₀ = 180 nM).

The series nevertheless has no observable cytotoxicity up to 100 μM. Ensuing pharmacokinetic optimization resulted in the development of two potent and orally bioavailable anti-fibrotic agents that were capable of dose-dependently reducing connective tissue growth factor gene expression in vitro as well as significantly reducing the development of bleomycin-induced dermal fibrosis in mice in vivo.

Kaiwa, Yusuke;Oka, Kouki;Nishide, Hiroyuki;Oyaizu, Kenichi research published 《 Facile reversible hydrogenation of a poly(6-vinyl-2,3-dimethyl-1,2,3,4-tetrahydroquinoxaline) gel-like solid》, the research content is summarized as follows. Polymers bearing hydrogen storage units store hydrogen gas via chem. bond formation, and have inherent advantages as quasi-solid polymeric hydrogen carriers, such as handling easiness and high safety. A recent study demonstrated that a poly(6-vinyl-1,2,3,4-tetrahydroquinoxaline) gel-like solid was dehydrogenated over 5 h under 120°C and air, and then the material was reversibly hydrogenated under 60°C and ambient hydrogen pressure in the presence of an iridium complex catalyst. The present work aimed to improve the dehydrogenation rate via the substitution of Me groups for hydrogen atoms on carbon atoms adjacent to the nitrogen atoms in the quinoxaline unit. The dramatic improvement was attributed to the electron donating property of Me group, and stabilization of the dehydrogenated state. The poly(6-vinyl-2,3-dimethyl-1,2,3,4-tetrahydroquinoxaline) gel-like solid was rapidly dehydrogenated within 2 h under the same mild conditions. This article provides a guideline for the mol. design of nitrogen heterocyclic compounds for rapid dehydrogenation.
