The synthesis and optical properties of novel triphenylamine containing 1,3,4-oxadiazole derivatives

Symmetrical 4,4′,4″-trisubstituted triphenylamine derivatives containing 1,3,4-oxadiazole moiety bearing long aliphatic chains have been synthesized by employing convenient and simple synthetic protocols. The structures of these target molecules were established by their analytical and spectral data. They exhibit good fluorescence properties with high quantum yield and show very efficient fluorescence quenching in presence of p-nitrotoluene.
