| 摘 要： | 合成了高分子金属配合物聚8-羟基喹啉镓(Gaqq3)n.利用红外吸收光谱、X射线衍射谱(XRD)研究了配合物的分子结构、物相结构;利用热重(TG)分析研究了配合物的热稳定性;利用紫外吸收光谱、荧光激发和发射光谱研究了该配合物的光物理性能.结果表明:(Gaqq3)n的热分解温度为443.6℃,具有较高的热稳定性.(Gaqq3)n的紫外吸收带位于250～500 nm,存在较强的带尾吸收,表明禁带中存在带隙缺陷态.(Gaqq3).的荧光激发带位于380～456nm,荧光发射峰位于568nm,为橙红光发射.光学带隙2.49 eV.与Gaq3相比,荧光强度有所减弱,这是由于次甲基相连的两个喹啉环的扭曲导致了(Gaqq3)n的刚性和共平面性不好;由于分子共轭体系的增大,使(Gaqq3)n分子的π电子更加离域化,导致了荧光发射峰发生了红移.(Gaqq3)n有望在有机电致发光器件和有机光伏器件中得到应用.

| Abstract: | A ligand 5,5'-methylene-bis(8-hydroxyquinoline)(Hqq)was synthesized by condensation reaction at low temperature and was subsequently coordinated to gallium ions to prepare the polymer of tis(5,5'-methylene-bis(8-hydroxyquinoline)gallium(Gaqq3)n.Both chemical structure and phase structure of the ligand and complexes were characterized by Infrared absorption spectrum and X-ray diffraction(XRD).The thermal stability of the complexes was studied by thermogravimetry(TG).The photo-physical properties of the compl... |
