Mononuclear Pt(II) Complexes and [Pt-Ag-Pt] Cluster: Controllable Syntheses, Structural Transition and Luminescence Modulation
Complexes [Pt(moppy)(PPh2Py)Cl] (1), [Pt(moppy)(PPh2Py)]PF6 (2) and [Pt2(moppy)2(CH3CN)2Ag(μ-PPh2Py)2](PF6)3 (3) have been synthesized through choosing suitable experimental condition to modulate the coordination mode of PPh2Py. Crystal structures indicate that 1 and 2 show distinct mononuclear structures, and complex 3 is a [Pt−Ag-Pt] cluster. In a CH2Cl2–H2O mixed solvent, complexes 1 and 2 can be interconverted upon alternately adding AgPF6 and NaCl. Complex 3 can dissociate into complex 2 in solution. These complexes reveal different luminescence. In deaerated acetone, complex 1 is non-luminescent, while 2 show green luminescence with main emission bands at 511 and 534 nm. Complexes 1 and 2 in solid state show similar green luminescence, but significant differences in quantum yield, Φ=7.4 % for 1, and Φ=17.6 % for 2. Compared to 1 and 2, complex 3⋅CH3COCH3 exhibits yellow solid-state luminescecne (Φ=14.1 %). In this paper, we discuss structural transitions among complexes 1–3 and luminescence modulation.
