A C^N Cycloplatinated(II) Fluorido Complex: Photophysical Studies and Csp3‒F Bond Formation

Abstract

<div>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.</div>

Synthesis, Reactivity, and Bonding of Gold(I) Fluorido–Phosphine Complexes

“…93,94 The perfluorinated phenyl ligand bends away from the biaryl substituent with a P1−Au1−C1 angle of 170.67(8)°. 9a crystallizes in the space group P2 1 /c, and the Au1−S1 distance of 2.3053 (11) Å compares well to other gold(I) coordination compounds with sulfur. 95…”

“…A similar reactivity was reported recently for a platinum(II) fluorido complex. 11 No conversion was observed with iodobenzene.…”
