Abstract

Increased resonance: The selective tuning of the optoelectronic properties of organic semiconductors is possible by enantiotropic resonance variation. Using resonance forms of N(+)=P-O(-) in a series of arylamine-phosphine oxide hybrids afforded low-voltage-driven phosphorescent OLEDs with outstanding performances.

Keywords: donor-acceptor systems; organic light-emitting diodes; phosphine oxides; phosphorescence; resonance variation.
