Electroluminescence from 400 to 700 nm (see right picture) is exhibited by an organic electroluminescent device based on (mdppy)BF (left picture) as emitter and a 1,1′‐biphenyl‐4,4′‐diamine derivative as a hole‐transporting material. The device emits white light with high efficiency and good color purity.
