The effect of electron-withdrawing substituents in asymmetric anthracene derivative semiconductors was written by Liu, Si;Zheng, Lei;Chen, Mingxi;Sun, Yajing;Wang, Peng;Li, Shuyu;Wu, Hongnan;Zhang, Xiaotao;Hu, Wenping. And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2021.Synthetic Route of C3H2BrNS This article mentions the following:
Three anthracene derivatives, referred to as 2-Ph anthracene (Ph-Ant), 2-thiazole anthracene (TZ-Ant), and 2-pentafluorophenyl anthracene (F5Ph-Ant), were designed and synthesized to reveal the effects of the electron-withdrawing substituents on the mol. packing structure and photoelec. properties of the anthracene core. As the electron-withdrawing abilities of the substituents increased, the mol. structures of the three semiconductors showed a progressive deterioration in intermol. interactions and mol. accumulation, and the photoelec. properties became worse. Interestingly, the energy levels of the three semiconductors showed gradually decreasing changes with an enhancement of the electron-withdrawing abilities of the substituents, indicating a possible strategy for fabricating n-type anthracene derivative semiconductor materials. In the experiment, the researchers used many compounds, for example, 2-Bromothiazole (cas: 3034-53-5Synthetic Route of C3H2BrNS).
2-Bromothiazole (cas: 3034-53-5) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Thiazole is a versatile building block for the construction and lead generation of new drug discoveries. Numerous diazole-based compounds are in clinical use as anticancer, antileukemic, antiinflammatory, antiviral, antifungal, antirheumatic, immunomodulator, and antiparasitic agents.Synthetic Route of C3H2BrNS
