A new blue fluorescent aromatic diamine, 2-(4,4′-diamino-4″-triphenylamine)-5-(4-dimethylaminophenyl)-1,3,4-oxadiazole, is synthesized in several steps. Based on this diamine four fluorescent imide-type polymers, a polyimide and three poly(amide-imide)s,

Three series of substituted 1,3,4-oxadiazoles were studied by 17O NMR spectroscopy. Chemical shifts values were correlated with empirical Hammett parameters as well as calculated bond lengths and chemical shielding values.

The dependence of the spectral-luminescence properties of substituted 2,5-diphenyl-1,3,4-oxadiazoles on the electronic nature of the substituents was studied.Experimental and theoretical studies confirm the electron-acceptor character of the oxadiazole ring and constitute evidence for the rather effective transmission of the electronic effects through the heteroring.
