Luminescence of Thin Films Based on 2,5-Diaryl-1,3,4-Oxadiazole and its Beryllium Chelate Complex

Chelate complexes BeL2 and ZnL2 with 2-[5-(2,4,6-trimethoxyphenyl)-1,3,4-oxadiazol-2-yl]phenol (HL) were synthesized. Their compositions were confirmed by thermogravimetric and IR spectroscopic analyses. Thin films of HL and BeL2 were spin coated on a glass substrate. The spectral and luminescent properties of the obtained compounds in solutions, solids, and films were studied. The optimal conditions for obtaining thin films were found. Their morphology was studied.
