Tunable Organophosphorus Dopants for Bright White Organic Light‐Emitting Diodes with Simple Structures

Abstract

Efficient white-light-emitting LEDs have been constructed by varying the substitution pattern of phosphole derivatives and chemical modification of their P atoms, producing thermally stable derivatives that are used as suitable dopants in a blue-light-emitting host. The devices exhibit high brightness and, due to their simple structures, current-independent CIE coordinates.
