In contrast to electron transport hosts, hole transport hosts are suitable for electron-dominated emitters. Scheme 3.36 shows the chemical structures of some typical hole transport host materials. A widely used hole transport host material for triplet emitters is... [Pg.334]

Recently, Shu and coworkers [64] used the Os(fppz) triplet emitter to improve the EL of the fluorene copolymer PF-Q (35) (Chart 4.14) [64]. A red-emitting PPLED ITO/PEDOT/2.4%Os(fppz) PF-Q (35)/TPBI (9)/Mg Ag showed an EQE of 6.6% and a maximum brightness of 10,400 cd/m2, which is almost ten times higher than that in a similar device without a triplet emitter. [Pg.432]

Clearly, using a triplet emitter with shorter excited state lifetime should improve the device efficiency. In 2002, Cao and coworkers [65] used iridium complexes Ir(ppy)3 (3) and its... [Pg.433]

Metal complexes with Schiff base ligands have useful applications in organic optoelectronics due to their outstanding photoluminescent (PL) and electroluminescent (EL) properties, and their ease of synthesis, which readily allows structural modification for optimization of material properties.28 Hamada and co-workers pioneered the use of zinc(II) Schiff base complexes as blue to greenish white emitters for EL devices. We have demonstrated Pt(II) Schiff base triplet emitters as yellow dopants for organic light-emitting devices... [Pg.375]

A typical multilayer device architecture containing triplet emitters is described in Fig. 31, and the resulting energy level scheme is shown in Fig. 32. ITO (indium tin oxide)-coated glass substrate is used as anode and on top of it a lOnm thick CuPc (copper phthalocyanine) hole injection layer is... [Pg.165]
