Research in the 2,5-Diaryl-1,3,4-oxadiazole Series. 1. Electronic Structures and Spectral-Luminescence Properties of Substituted 2,5-Diphenyl-1,3,4-oxadiazoles

Article abstract of DOI:10.1007/BF00512808

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.
