Preparation and Fluorescence Properties of Dendritic 8-Hydroxyquinoline and their Zinc Complexes

Abstract:

Two different dendritic 8-hydroxyquinoline ligands were synthesized through convergent approach, and the products were characterized by nuclear magnetic resonance (NMR) and infrared spectrometry (IR); the fluorescence properties of the dendritic 8-hydroxyquinoline ligands and the corresponding metallic complexes with Zn (II) were also studied by fluorescent spectrometry. The results show that the dendritic modifications of 8-hydroxyquinoline nucleus enhanced the intensity of luminescence, and the peripheral functional groups in the dendritic structure may affect the property of luminescence; the obvious red shift observed in the fluorescence profile of dendritic 8-hydroxyquinoline zinc provides it prospect of extensive application in the discipline of organic electroluminescent materials.
