Synthesis and Characterization of a Novel Diphenylamine-Thiophene Compound for Blue Organic Light-Emitting Diodes

Article Preview

Abstract:

Diphenylamine and thiophene compounds are promising materials for organic light-emitting diodes (OLEDs). We report here, the synthesis and optical property of a novel small molecular weight derivative, N4.N4,N4'.N4'-tetrakis (4- (thiophen-2-yl) phenyl)-[1,1'-bipheny-4,4'-diamine (TPPA). The target molecule was synthesized using 4,4'-dibromobiphenyl as the starting material, and the proceeding reactions included bromination, Buchwald and Suzuki coupling reactions. According to the optical characterization of it, the absorption peak and excitation peak is at 351nm and 412 nm, respectively. The luminescence quantum yields (LQY) of TPPA is measured at 61.3%.
