The Schiff Base compound, 2-(pyrene-1-yl alkylidene) hydrazino-4-pyridyl thiazole, was obtained by the reaction of ω-bromoacetyl pyridine hydrobromide salt (1) and N-(pyren-1-yl alkylidene)aminothiourea(2). Previously, the bromination of acetyl pyridine afforded ω-bromoacetyl pyridine hydrobromide salt (1) and the chemical reaction of acyl-pyrene and aminothiourea provided the N-(pyren-1-yl alkylidene) aminothiourea(2). The final product Shiff Base (3) was detected by 1H NMR, MS, IR and Elemental analysis. The results show that the structure of the target compound(3) is part of multiple aromatic conjugation system with donor-accept substituent and better thermostabilities is exhibited in the research as its higher melting point of 240 C. In conclusion, it has potential applications as a nonlinear optical material used for devices. © 2015, North China Institute of Technology. All right reserved.
