recognized fluorophores. We report herein synthesis and structural characterization of novel 1,3,4-oxadiazole-based compounds functionalised by salicylaldehyde or o-vanillin moieties. Solution absorption and emission spectroscopy performed on the resulted compounds indicated the essential influence of the established (intra and/or intermolecular) hydrogen bonds onto the opticalproperties.
