Hybrid nanospheres of silica covalently containing yellow-emitting cationic iridium(iii) complex: preparation and application in white light-emitting diodes

Abstract

A yellow-emitting cationic iridium(III) complex [(dfppy)2Ir(TBD)]PF6 (TBD: N4,N4'-Bis(3-(triethoxysilyl)propyl)-[2,2'-bipyridine]-4,4'-dicarboxamide; dfppy: 2-(2,4-difluorophenyl)pyridine) containing hydrolysable alkoxysilanes was synthesized. Then, a series of silica-based hybrid nanospheres with diameters around 400 nm were prepared via...
