Realization of high-efficiency/high-luminance small-molecule organic light-emitting diodes: Synergistic effects of siloxane anode functionalization/hole-injection layers, and hole/exciton-blocking/electron-transport layers

Realization of high-efficiency/high-luminance small-molecule organic ligh-emitting diodes (OLED) was discussed. OLEDs were fabricated by combining thin, covalently-bound triarylamine hole injection/adhesion interlayers. Results showed that enhancing hole injection via covalently linked TPDSi2 injection/adhesion interlayers can be synergistically combined with BCP hole/excition-blocking interlayers to yield highly efficient small molecule OLEDs
