Abstract

The synthesis and properties of new hole-transporting amorphous molecular materials with high glass-transition temperatures are described. They include 4,4',4"-tris[9,9-dimethylfluoren-2-yl(phenyl)amino]- triphenyl-benzene (TFAPB), 4,4',4"-tris[9,9-dimethylfluoren-2-yl(4-methylphenyl)amino]triphenylbenzene (MTFATB), and 4,4',4"-tris[bis(9,9-dimethylfluoren-2-yl)amino]triphenyl-benzene (TBFAPB). It is shown that they function well as hole-transporting materials in thermally stable organic light-emitting diodes.
