Syntheses, Emission Properties and Intramolecular Ligand Exchange of Zinc Complexes with Ligands belonging to the Tmpa Family.
Sprache des Titels:
The zinc complexes [(L1)2Zn(MeOH)2](OTf)2, [(L1)ZnCl2], [(L2)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.
