双核铜(Ⅰ)配合物的合成及其固态发光性质的研究

Syntheses and Solid-state Luminescence Properties of Binuclear Copper (Ⅰ) Complexes

摘要: 报道了两个双核一价铜配合物(PPh₃)₂Cu(μ-X)₂Cu(PPh₃) (X = Br (1)；Cl (2))的合成以及配合物1的晶体结构，并研究了铜(Ⅰ)配合物1和配合物2的固态发光特性.研究表明：配合物1和配合物2在室温中表现出强的固态绿色荧光，其发光主要来源于受配位铜(Ⅰ)金属离子影响的三苯基膦(PPh₃)配体.

Abstract: Two binuclear cuprous complexes (PPh₃)₂Cu(μ-X)₂Cu(PPh₃) (X = Br (1); Cl (2)), are synthesized and characterized by single-crystal X-ray diffraction for 1. It is demonstrated that complexes 1 and 2 exhibit strong green solid-state photoluminescence at ambient temperature mainly originating from the phosphine ligands PPh₃ coordinating to the metal Cu(Ⅰ) ions.
