on 3,5‐dipyridylbenzene (dpb) N,C,N‐chelate PtII compounds by synthesizing compound 4, Pt(Bdpb)Cl, which has a BMes2 group at the 4′‐position of the benzene ring. Compound 4 has a phosphorescent emission band at 485 nm and ΦPL=0.70. Highlyefficientblue‐green electroluminescent (EL) devices with a double‐layer structure and compounds 1, 3 or 4 as the phosphorescent dopant have been fabricated. At 100 cd m−2
