Abstract

This work reports the synthesis and characterization of a new C^N-based cycloplatinated(II) fluorido complex [Pt(ppy)PPh3)F] involving a Pt‒F bond. The new complex is highly luminescent in green area with a high quantum yield of 94.6% at 77K. A comparison study of the heavier of halogen derivatives reveals a descending emission quantum yield order of F > Cl > Br > I. Time-dependent density functional theory (TD-DFT) calculations ascribe the decreased emission efficiency to the decreasing trend of ILCT transition from F to I, which accounts for the major radiative pathway.
