Novel cyclometalated Pt(II) complexes with interesting luminescent properties

Organometallic complexes of transition-metals have recently received considerable attention as phosphorescent emitters for Organic Light Emitting Diodes (OLEDs), owing to their remarkable luminescent properties1. In particular, various platinum(II) complexes with a cyclometallated 1,3-di(2-pyridyl)benzene ligand seem very promising in this respect because they are highly emissive.2 This observation prompted us to prepare new cyclometallated Pt(II) complexes with a substituted 1,3-di(2-pyridil)benzene ligand (see figure) to get a better understanding of the effect on the emission and quantum yields of different R substituents and various Y ancillary ligands. It turned out that all the prepared complexes are highly luminescent and can be used for the preparation of light-emitting devices. Details on this study will be presented.
