New PtII complexes of bidendate Ph2S(=N(Ph2)S≡N)2 (ndsdsd) ligand were prepared, including the homoleptic complex, i.e., [Pt(ndsdsd)2](hfac)2 (1) (hfac: 1,1,1,5,5,5-hexafluoro-2,4-pentanedionato), and the heteroleptic complexes, [Pt(N^N)(ndsdsd)]X2 [N^N = 1,10-phenanthroline (phen) (2), 4,7-diphenylphenanthroline (bathophen) (3); X = PF6 (a) and ClO4 (b)] and [Pt(C^N)(ndsdsd)]X [C^N = 2-phenylpyridine (ppy) (4) and benzo[h]quinoline (bzq) (5); X = PF6 (a) and ClO4 (b)]. The complexes were characterized by IR, NMR spectroscopy, and elemental analysis. The molecular structures of complexes 1, 2a, and 4b have been elucidated by X-ray crystallographic analysis. The photophysical properties of all complexes were examined. Complexes 2 and 3a are very weakly luminescent in solution, whereas they show highly emissive in the solid state (Φem = 0.11–0.27).
新的双齿配体Ph2S(=N(Ph2)S≡N)2 (ndsdsd)铂(II)配合物被制备,包括同配合物,即[Pt(ndsdsd)2](hfac)2 (1)(hfac:1,1,1,5,5,5-六氟-2,4-戊二酮),以及异配合物[Pt(N^N)(ndsdsd)]X2 [N^N = 1,10-菲咯啉 (phen) (2)、4,7-二苯基菲咯啉 (bathophen) (3);X = PF6 (a) 和 ClO4 (b)]和[Pt(C^N)(ndsdsd)]X [C^N = 2-苯基吡啶 (ppy) (4) 和苯并[h]喹啉 (bzq) (5);X = PF6 (a) 和 ClO4 (b)]。这些配合物通过红外光谱、核磁共振光谱和元素分析进行了表征。配合物1、2a和4b的分子结构通过X射线晶体学分析得以阐明。所有配合物的光物理性质均进行了检查。配合物2和3a在溶液中发光非常微弱,而在固态下则表现出高度发射性(Φem = 0.11–0.27)。
