Luminescent Heterobimetallic Pt-Au Complexes Bearing -Heterocyclic Carbenes (NHCs) as Potent Anticancer Agents.

This study aims to probe into new series of heterobimetallic Pt-Au complexes with a general formula of [Pt(-MeCH)(dfppy)(μ-dppm)Au(NHC)]OTf, NHC = IPr, ; IMes, ; dfppy = 2-(2,4-difluorophenyl)pyridinate; dppm = 1,1-bis(diphenylphosphino)methane, which are the resultant of the reaction between [Pt(-MeCH)(dfppy)(κ-dppm)], , with [AuCl(NHC)], NHC = IPr, ; IMes, , in the presence of [Ag(OTf)]. In the heterobimetallic complexes, the dppm ligand is settled between both metals as an unsymmetrical bridging ligand. Several techniques are employed to characterize the resulting compounds.

Photophysical Properties and Kinetic Studies of 2-Vinylpyridine-Based Cycloplatinated(II) Complexes Containing Various Phosphine Ligands.

A series of cycloplatinated(II) complexes with general formula of [PtMe(Vpy)(PR)], Vpy = 2-vinylpyridine and PR = PPh (); PPhMe (); PPhMe (), were synthesized and characterized by means of spectroscopic methods. These cycloplatinated(II) complexes were luminescent at room temperature in the yellow-orange region's structured bands. The PPhMe derivative was the strongest emissive among the complexes, and the complex with PPh was the weakest one.
