Ionic Platinum(II)–Imidobis(diphenylthiophosphinato) Complexes: Preparation, Structure, and Thermal Behavior

Mixed-ligand Cu(I) complexes have attracted attention as alternatives to the noble-and/or rare-metal complexes, because of their remarkable photofunctions. To develop mixedligand Cu(I) complexes with rich photofunctions, an investigation of a suitable combination of ligands has captured more and more research interests. Herein, we report the first examples of emissive heteroleptic diphosphine-disulfide Cu(I) complexes combined with diphosphine ligands. The systematic study using a series of diphosphine ligands revealed that large π-conjugated bridging moieties between the two P atoms in the diphosphine ligands result in higher light-emission performance. When the diphosphine ligand w a s ( R ) -B I N A P ( ( R ) -B I N A P = ( R ) -( + ) -2 , 2 ′ -b i s -(diphenylphosphino)-1,1′-binaphthyl), the Cu(I) complex had an emission quantum yield (Φ em ) of 0.13 and a long emission lifetime (τ em = 118 μs).

Ionic Platinum(II)–Imidobis(diphenylthiophosphinato) Complexes: Preparation, Structure, and Thermal Behavior

Abstract: 2 -H)] [(L-L = dppm(1), dppe(2), dppp(3)]. All of these have been characterized by 1 H, 13 C ,31 P{ 1 H} NMR, FTIR, and elemental analysis. These complexes were also examined by TGA, DTA, and DSC analysis. Complexes 2 and 3 were crystallographically characterized.
