摘要
Refluxing equimolar amounts of acylhydrazides with triethyl orthoformate in o-xylene yielded 2-aryl-1,3,4-oxadiazoles luminescing with high quantum yields in polar and nonpolar solvents (λm fl ax 299–349 nm, φ 0.20–0.62). The only exception was 2-(1,3,4-oxadiazol-2-yl)phenol emitting intensely only in highly polar aprotic DMSO (λmaxfl 350 nm, φ 0.19).
