Synthesis, characterization and fluorescent properties of 5-(aryliminomethyl)quinaldine-8-ol derivatives and their trinuclear zinc complexes

Add time:08/27/2019    Source:sciencedirect.com

A series of 5-[1-(arylimino)methyl]quinaldine-8-ol derivatives L1–L5 and their trinuclear zinc(II) complexes (C1–C5) were synthesized. The compounds L1–L5 were fully characterized by the FT-IR spectra, NMR measurement and elemental analysis, meanwhile the zinc complexes C1–C5 were characterized by the FT-IR spectra and elemental analysis as well as the single crystal X-ray diffraction of a representative complex C3, which revealed a trinuclear zinc complex bearing six organic ligands. The fluorescent properties of both organic compounds and the zinc complexes have been carefully investigated by the UV–Vis absorption in various solvents, indicating the significant influences of the solvents and also double exponential decays.
