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.
