摘要

The zinc complexes [(L1)_2Zn(MeOH)_2](OTf)_2, [(L1)ZnCl_2], [(L_2)ZnCl_2], [(L_2)Zn(OTf)(H _2O)]OTf and [(Me-bispic)ZnCl_2] 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)ZnCl 2] 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.
