Tris-cyclometalated iridium(III) styryl complexes and their saturated analogues:: Direct functionalization of Ir(4-Me-ppy)3 and hydrogen transfer process

A new series of tris-cyclometalated Ir(III) Styryl Complexes and their saturated analogues have been synthesized; the former are formed by functionalization of Ir(4-Me-ppy)(3) and the latter from a hydrogen transfer process to the styryl groups. Their luminescence properties have been investigated.
