| 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）]ClO4（1）和[Cu（mmbpy）（dppb）]ClO4（2）。研究结果表明，铜（Ⅰ）配合物1和2均表现为扭曲变形的N2P2四面体几何构型，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。 | |

| Abstract: 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. | |
