Synthesis of OLED Materials of Several Triarylamines by Palladium Catalysts and Their Light Emitting Property

Abstract

Primary aryl amines reacted with aryl halides to give the secondary aryl amines by the catalysis of [Pd(dba)2/P(t-Bu)3] at 80 °C in toluene. Secondary aryl amines reacted with 1-bromo-pyrene and 9-bromo-phenanthrene and 2,7-dibromo-9H-fluorene to afford the OLED material of aminopyrene derivatives and aminophenanthrene derivatives and diamino-9H-fluorene type by the catalysis of [Pd(OAc)2/P(t-Bu)3] at 120 °C in o-xylene. The product structures were established by 1H NMR, 13C NMR, 13C(DEPT), HRMS spectra. Physical properties were examined by UV-vis, PL and DSC spectra.
