yield. These two compounds were subjected to the following characterization techniques: single crystal X-ray diffraction, elemental analysis, infrared, mass, 1H NMR, 13C NMR spectroscopy and thermogravimetric analysis. The Schiff bases A and B belong to the monoclinic P21/c space group. Their crystal structures are stabilized by intra and intermolecular hydrogen bonds, as well as by weak π−π stacking.
摘要 基于两种新的有机材料供体受体系统,即 N,N-二甲基-4-((E)-(4-((E)-((5-phenylthiophen-2-yl)methylene)amino)phenyl)diazenyl)成功合成了苯胺A和(E)-4-((E)-(4-硝基苯基)二氮烯基)-N-((5-苯基噻吩-2-基)亚甲基)苯胺B。两种化合物(A 和 B)都是通过 N, N-Dimethyl-4,4'-azodianiline 或 4-(4-nitrophenylazo)aniline 与 5-phenylthiophene-2- 甲醛之间的缩合反应合成的,77% 和 83 % 屈服。对这两种化合物进行以下表征技术:单晶 X 射线衍射、元素分析、红外、质谱、1H NMR、13C NMR 光谱和热重分析。席夫碱 A 和 B 属于单斜 P21/c 空间群。它们的晶体结构通过分子内和分子间氢键稳定,以及弱 π−π
