锌配合物[（L1）（2）Zn（MeOH）（2）]（OTf）（2）、[（L1）ZnCl 2]、[（L-2）ZnCl 2]、[（L2）Zn（OTf）（H2O）]OTf和[（Me-bispic）ZnCl 2]的配体N-[（2-吡啶基）甲基]-2，2 '-二吡啶胺（L1），合成并表征了N-[双（2-吡啶基）甲基]-2-吡啶胺（L2）和N-甲基-[双（2-吡啶基）甲基]胺（Me-bispic）。还合成了配体L1和L2的第一铜（I）络合物并进行了结构表征。[（L1）ZnCl 2]在溶液中表现出意想不到的流动行为，并揭示了锌离子配位层中有趣的分子内配体交换机制。此外，在紫外光激发下观察到强的蓝光发射。
The zinc complexes [(L1)(2)Zn(MeOH)(2)](OTf)(2), [(L1)ZnCl2], [(L-2)ZnCl2], [(L2)Zn(OTf)(H2O)]OTf and [(Me-bispic)ZnCl2] of the ligands N-[(2-pyridyl)methyl]-2,2'-dipyridylamine (L1), N-[bis(2-pyridyl)methyl]-2-pyridylamine (L2) and N-methyl-[bis(2-pyridyl) methyl]amine (Me-bispic) were synthesised and characterised. The first copper(I) complexes of the ligands L1 and L2 were also synthesised and structurally characterised. [(L1)ZnCl2] showed unexpected fluxional behaviour in solution and revealed an interesting intramolecular ligand exchange mechanism in the coordination sphere of the zinc ion. Furthermore, strong blue emission was observed under UV-light excitation.
