一种新型双8-羟基喹啉-锌高分子配合物的合成及光致发光性能

Synthesis and photoluminescent properties of a novel bis(8-hydroxyquinoline) zinc complex

采用Wittig-Horner反应合成了一种新型双8-羟基喹啉配体,并将此配体与金属锌进行配位反应,制备与其对应的高分子配合物。采用红外、核磁和紫外可见光谱等表征了配体及其配合物的结构和光物理性能,利用荧光光谱研究了高分子配合物的光致发光性能,确定了其最大发射峰位(550 nm)。该配合物是一种理想的橙红色发光聚合物材料。

A new ligand based on bis（8-hydroxyquinoline） was synthesized by the Wittig-Horner reaction and was subsequently coordinated to zinc ions to prepare the corresponding zinc complex. The ligand and its complex were characterized by FT-IR, IH-NMR and UV-visible spectroscopy. The photoluminescent performance of the zinc complex was investigated and it was found to show a strong fluorescent emission peaking at 550 nm in solution.
