摘要

Abstract Novel yellow azo dyes were synthesized by diazotization of aromatic amines followed by coupling with 2-morpholin-4-yl-1, 3-thiazol-4 (5H)-one and fully characterized. The geometries of the synthesized dyes for azo and hydrazone tautomeric forms were optimized using B3LYP, CAM-B3LYP and M06 functional and 6-31G (d) and 6-311++ G (d, p) basis sets, also their electronic excitation properties were evaluated using density ...
