Synthesis and Photophysical Characterization of Dendritic 8-Hydroxyquinoline Complexes

This is the authors' abstract. We don't add key points for this paper.

Two kinds of dendritic 8-hydroxyquinoline ligands were efficiently prepared by convergent method, and characterized by IR, 1H NMR, 13C NMR and MS. The fluorescent properties of dendritic ligands and their Zn(II) complexs were studied. The results indicate that this new methold is readily, which generates virtually no by-products. All dendritic 8-hydroxyquinoline derivatives have good solubility in most of organic solution. These dendritic derivatives show good fluorescence, which can be anticipated as a type of important functioned materials for OLEDs.
