PRODUCTION METHOD OF TPPA(TRIS(4-(PYREN-1-YL)PHENYL)AMINE) USING A TRIPHENYL-AMINE MATERIAL AND AN ORGANIC LIGHT-EMITTING DIODES USING TPPA

摘要

PURPOSE: A tris(4-(pyren-1-yl)phenyl)amine is provided to enable use as a hole transport layer due to excellent hole transport ability and to obtain organic light-emitting diodes with improved performance.;CONSTITUTION: A method for preparing tris(4-(pyren-1-yl)phenyl)amine represented by chemical formula 1 comprises a step of reacting tris(4-bromophenyl)amine, 1-pyreneboronic acid, K2CO3, and palladium tetrakis(triphenylphosphine) in a THF/H2O solution through heating and mixing. An organic electroluminescent device uses an excimer of a material of chemical formula 1.;COPYRIGHT KIPO 2011
