Synthesis and Luminescent Properties of Novel Metal-organic Coordination Polymers Based on Bisphenol A

Four novel bis-Schiff base ligands and their zinc(Ⅱ) coordination polymers were synthesized from the bisalicylaldehydes based on the backbone of bisphenol A. The structures, thermal stabilities, luminescent properties and energy bands were investigated by infrared spectra, ¹H NMR, TG curve, UV-Vis absorption spectra and fluorescence emission spectra. The results showed that these complexes are thermally stable with high decomposition temperature at 405 ~443 ℃. The complexes emit blue-green fluorescence with the maximum emission peaks at 493 ~503 nm. Their quantum yields are close to that of the repoted literatures, the band gap is about 3.04 ~3.23 eV. The results above suggest that the novel coordination ploymers can be utilized as good organic electroluminescent materials.
