Crystallographic and DFT examination of the metalloligands [AuAr(CNPy-4)] (Ar = C6F5 (1), C6F3Cl2-3,5 (2)) and their silver complexes [Ag[AuAr(CNPy-4)]2](BF4) (3 and 4) support that the marked luminescence red-shifts observed on moving from 1 to 2, from 1,2 to 3,4, or upon grinding, are not caused by electronic differences (either by changing the aryls C6F5/C6F3Cl2, or by N coordination to silver)
金属配体[AuAr(CNPy-4)](Ar = C 6 F 5(1),C 6 F 3 Cl 2 -3,5(2))及其银配合物[Ag [AuAr(CNPy) -4)] 2 ](BF 4)(3和4)支持所标记发光红移上移动从观察1至2,从1,2至3,4,或在研磨,不会引起电子差异(通过更改芳基C 6 F 5/ C 6 F 3 Cl 2,或通过与银的N配位),也可以通过不存在的Au⋯Ag相互作用来实现。它们总是由于结构变化而干扰更强的π-π堆积,从而允许较短的Au⋯Au相互作用。
