摘　　要：合成并表征了2个新的基于6-甲氧羰基-4,4′-二甲基-2,2′-联吡啶的单核铜(Ⅰ)双膦配合物[Cu(mmbpy)(dppp)]ClO_4(1)和[Cu(mmbpy)(dppb)]ClO_4(2)。研究结果表明,铜(Ⅰ)配合物1和2均表现为扭曲变形的N_2P_2四面体几何构型,其P-Cu-P键角受辅助双膦配体控制。在常温下,这2个铜(Ⅰ)配合物在固态时均具有发光性质,并且相对于双膦配体亚甲基链的长度,P-Cu-P键角对其光物理性质的影响更为显著。在2,2′-联吡啶环上引入2个甲基取代基对改善铜(Ⅰ)配合物的发光性能也被证明是有效的。Two new mononuclear copper（Ⅰ） diphosphine complexes based on 6-methoxycarbonyl-4,4＇-dimethyl-2,2＇-bipyridine （mmbpy）,[Cu（mmbpy）（dppp）]ClO4 （1） and [Cu（mmbpy）（dppb）]ClO4 （2）, have been synthesized and characterized. It is revealed that Cu（Ⅰ） complexes 1 and 2 all exhibit distorted N2P2 tetrahedral geometries with varied P-Cu-P angles regulated by auxiliary diphosphine ligands. The two Cu（Ⅰ） complexes are all emissive in the solid state at ambient temperature, and their photophysical properties are more markedly influenced by the P-Cu-P angle than the methylene chain length of diphosphine. It is also demonstrated that the introduction of two methyl substituents into the 2,2＇-bipyridyl ring is effective for improving luminescence properties of Cu（Ⅰ） complexes.
