Mao, Xiaoyu;Liu, Yiwei;Zeng, Jin;Wang, Xiaohui;Islam, Monarul Md;Chen, Ming;Chen, Qing;Feng, Xing research published 《 Synthesis and photophysical properties of quinoxaline-based blue aggregation-induced emission molecules》, the research content is summarized as follows. A series of quinoxaline-based compounds 1-4 have been synthesized by a palladium-catalyzed cross-coupling reaction and their photophys. properties have been extensively studied. Compounds 1-4 show deep blue light emission both in solution (λ_em ≤ 425 nm, Commission Internationale de L′Eclairage y (CIEy) ≤ 0.03) and in the solid state. Moreover, compounds 1-3 show a non-typical aggregation-induced enhanced emission (AIEE), which would be effective deep blue light-emitting materials. The DFT calculation indicated that the HOMO energy levels of compounds 1-3 are distributed throughout the mol., and the LUMO energy levels are mainly concentrated on the quinoxaline group. However, the HOMO of compound 4 is mainly on the benzene ring at 2,3 position, and the LUMO is distributed both of the quinoxaline and the benzaldehyde group at the 6,7 position.

Maeng, Jee Hyun;Braveenth, Ramanaskanda;Jung, Young Hun;Hwang, Soon Jae;Lee, Hyuna;Min, Hye Li;Kim, Jun Yun;Han, Chang Wook;Kwon, Jang Hyuk research published 《 Efficiency enhancement in orange red thermally activated delayed fluorescence OLEDs by using a rigid di-indolocarbazole donor moiety》, the research content is summarized as follows. The development of orange-red thermally activated delayed fluorescence (TADF) materials with good optoelectronic and electroluminescence properties are full of challenges due to limited mol. designs. Herein, we investigated a series of materials using dimethylacridine (DMAC) and diindolocarbazole (DI) donor with dibenzo [a, c] phenazine (DBP) acceptor, and compared the characteristics of all synthesized materials as emitters. Due to lower singlet energy level, the rate constant of internal conversion (k_IC) contribute to nonradiative decay cannot be ignored at the orange-red region. Therefore, employing rigid donor and acceptor moieties play a major role in suppressing kIC. We observed that employing a rigid donor of DI at β position enhanced the PLQY of 96.1% when compared to acridine based emitters. 5-(dibenzo [a, c] phenazin-11-yl)-10, 15-diphenyl-10,15-dihydro-5H-diindolo [3, 2-a:3′, 2′-c] carbazole (β-DI-DBP) based OLED device showed better current efficiency (CE_max) of 47.1 cd/A and maximum external quantum efficiency (EQE) of 23.8%. This work demonstrates a better approach towards high PLQY orange red TADF material development.

In the current study, fifteen new Quinazoline-benzimidazole hybrids I (R = H, 4-nitro, 4-chloro, 4-fluoro, 4-bromo; R¹ = Ph, 3,4-dimethoxyphenyl, 4-chlorophenyl), II (R² = trifluoromethyl, 4-bromo-2-florophenyl, 8-chloroquinolin-3-yl, naphthalen-2-yl) and III were designed, synthesized, and evaluated for their antimicrobial activity against S. aureus ATCC 29213 and M. tuberculosis H37Rv. These studies led to the identification of nine compounds potent antibacterial agents I (R = 4-nitro, R¹ = Ph; R = 4-chloro, R¹ = Ph; R = H, R¹ = Ph; R = 4-fluoro, R¹ = Ph; R = 4-nitro, R¹ = 3,4-dimethoxyphenyl; R = 4-chloro, R¹ = 3,4-dimethoxyphenyl; R = H, R¹ = 4-chlorophenyl; R = 4-fluoro, R¹ = 4-chlorophenyl) and II (R² = 8-chloroquinolin-3-yl) with MICs in the range of 4-64μg/mL. Further, these selected compounds were found to possess potent antibacterial potential against a panel of drug-resistant clin. isolates which include methicillin and vancomycin-resistant S. aureus.

Lv, Guangxin;Jensen, Elynn;Shen, Chengtian;Yang, Kexin;Evans, Christopher M.;Cahill, David G. research published 《 Effect of Amine Hardener Molecular Structure on the Thermal Conductivity of Epoxy Resins》, the research content is summarized as follows. Epoxy resins with enhanced thermal conductivity are in great demand to improve the thermal management of elec. motors. However, the thermal conductivity of epoxy resin is typically low, comparable to 0.2 W/m-K, and a predictive understanding of the connection between mol. structure and thermal conductivity is not yet established. In this work, we present data for the thermal conductivity of seven thermosets synthesized from one com. available diepoxide (resorcinol diglycidyl ether) and seven phenylenediamines to systematically examine the dependence of thermal conductivity on the mol. structure of the phenylenediamine hardener. Variations in the mol. structure of phenylenediamines, e.g., positions of amine groups and the addition of electron withdrawing group, produce up to a factor of 2 change in the thermal conductivity of the cured resins. The highest thermal conductivity of 0.27 W/m-K is obtained with 5-chloro-m-phenylenediamine; the lowest thermal conductivity of 0.14 W/m-K is obtained with o-phenylenediamine. Thermal conductivities of these seven epoxy resins are 10-40% lower than the prediction of the min. thermal conductivity model.

Liu, Can;Sadeghzadeh, Seyed Mohsen research published 《 CdSnO₃/SnD NPs as a Nanocatalyst for Carbonylation of o-Phenylenediamine with CO₂》, the research content is summarized as follows. In order to carbonize o-phenylenediamine with CO₂, an effective approach was used with UV light irradiation by Sn(IV) doping DFNS (SnD) supported CdSnO₃ as a catalyst (CdSnO₃/SnD). In this catalyst, SnD with the ratios of Si/Sn in the range of 6 to 50 were obtained using the Direct Hydrothermal Synthesis (DHS), and the nanoparticles of CdSnO₃ on the surfaces of SnD were reduced in situ. Scanning Electron Microscope, X-ray Diffraction, Fourier Transform IR Spectroscopy, X-ray Energy Dispersive Spectroscopy, and Transmission Electron Microscopy were utilized for characterizing CdSnO₃/SnD. It was found that CdSnO₃/SnD nanostructures could be used for synthesizing o-phenylenediamines due to their effective and novel catalytic behavior through the reaction between o-phenylenediamines and CO₂.

In this process, BH₃NH₃ served multifunctional roles, acting as a reducing agent and a formylation catalyst.
