Abstract
Symmetrical 2,5-disubstituted thiophene derivatives containing 1,3,4-oxadiazole moiety bearing different aromatic substitutions were synthesized by employing convenient and simple synthetic protocols using thiophene-2,5,dicarboxylic acid as a starting material. The structures of these target molecules were established by their analytical and spectral data. The photophysical and electrochemical studies were carried out on these compounds and found that they exhibit good fluorescent properties with high quantum yield.
Symmetrical 2,5-disubstituted thiophene derivatives containing the 1,3,4-oxadiazole moiety were synthesized from the corresponding thiophene 2,5-dicarboxylic acid. The Photophysical and electrochemical properties revealed that these compounds are good fluorescent materials with high quantum yield for OLED applications.
