A thermally stable hole injection material for use in organic light-emitting diodes

New discotic-shaped azomethines with triphenylamine moieties: Thermal, structural behaviors and opto-electrical properties

“…Many TPA derivatives were tested as hole-transporting materials in light emitting diodes construction [10][11][12][13][14]. Among the huge group of molecules and macromolecules with TPA units also poly(azomethine)s were investigated by few research groups [15][16][17][18][19][20][21] for OLEDS applications.…”
