Organic luminophore 2-(biphenyl-4-yl)-5-phenyl-1,3,4-oxadiazole (PBD, III) was converted by series of reaction into thioamide VIII which cyclized with substituted bromoacetylarenes X to give the bifluorophore system XI. The thiazole analog XIII was obtained by analogous reaction of bromoacetyl derivative V with thiobenzamide. All the thus-prepared compounds exhibit pronounced fluorescence in solution as well as in the crystalline state.
