Orange and Yellow Crystals of Copper(I) Complexes Bearing 8-(Diphenylphosphino)quinoline: A Pair of Distortion Isomers of an Intrinsic Tetrahedral Complex
the 2O and 2Y complexes showed a “flattening distortion”, meaning that the dihedralangle between the two chelate planes were off-perpendicular and oriented toward opposite directions, which resulted in a pair of distortion isomers: syn clinal (sc: 2O) and anti clinal (ac: 2Y). 31P CP-MAS NMR spectroscopy indicated that 2O and 2Y could be distinguished. Both isomers exhibited inequivalent P atoms, but

Metal‐containing dithienylethenes offer new opportunities for variations in photochromic behavior. This work reports a series of copper(I) complexes containing dithienylethene‐based bidentate phosphine ligands displaying varying photochromic properties. A copper dimer is used as a common precursor, allowing diverse photochromic functionality to be achieved. Calculations show that ring closing of the

Abstract A series of cyclometalated 2-(2′-pyridyl)phenyl}platinum(II) complexes having 8-quinolylphosphines, 8-(dimethylphosphino)quinoline (L1), 8-(diphenylphosphino)quinoline (L2), 2-methyl-8-(diphenylphosphino)quinoline (L3), and 2-phenyl-8-(diphenylphosphino)quinoline (L4), were prepared and their molecular structures and spectroscopic properties were investigated. The single-crystal X-ray analysis
摘要一系列具有8-喹啉基膦,8-(二甲基膦基)喹啉(L1),8-(二苯基膦基)喹啉(L2),2-甲基-制备了8-(二苯基膦基)喹啉(L3)和2-苯基-8-(二苯基膦基)喹啉(L4),并研究了它们的分子结构和光谱性质。[Pt(ppy)(Ln)](BF4或OTf)Cn; n = 1-4,ppy- = 2-(2'-吡啶基)苯基,OTf- =三氟甲磺酸盐}揭示了复杂阳离子的顺式(P,C)构型,尽管方平面PtII配位几何结构明显扭曲。特别是,在具有空间要求的8-喹啉基膦(L3和L4)的配合物C3和C4中,不仅观察到PtII配位球的四面体形变,而且还观察到PtII中心与平面螯合环的偏离,即观察到螯合喹啉基膦配位的包络型扭曲。所有配合物在溶液中对添加卤化物阴离子都是稳定的。然而,由于受温度影响的1H NMR光谱中观察到由于扭曲的配位球反转受限,络合物C3和C4的通量行为。
