Abstract

Abstract: A novel compound 2,6-di(4’-bisphenylaminostilbenyl)benzo[1-2,4-5]bisoxazole have been designed and synthesized with triphenylamino aldehyde and 2,6-bis(4-chloromethyl phenylene)benzo [1-2,4-5]dioxazole through Wittig-Horner reaction,that simultaneously taking triphenylamino as a hole transporting unit and benzobisoxazole as an electron transporting unit into the stilbene can evidently enhanced its light-emitting and light quantum efficiency.Its chemical structure has been determined by UV-Vis,IR,¹HNMR and EA,and photo-luminescent properties have also been researched.The results indicated that the synthesized compound has trans-stilbene structural character and can be used as small molecular blue light-emitting material.

Key words: 2,6-di(4’-bisphenylaminostilbenyl)benzo[1-2,4-5]bisoxazole, Wittig-Horner reaction, organic synthesis, light-emitting material
