| 摘 要： | 基于Wittig-Horner反应, 以对氯甲基苯甲酸甲酯、亚磷酸三乙酯、对苯二甲醛为主要原料, 经酯化、缩合得到二苯乙烯型荧光单体, 研究了各种反应条件对单体合成的影响. 将二苯乙烯型荧光单体高分子化得到了水溶性好、荧光性强、稳定性与安全性高的荧光聚合物. 用红外光谱对荧光单体结构进行了表征, 用紫外及荧光分光光度计对荧光单体及聚合物的荧光性能进行了研究. 结果表明: 荧光单体聚合后紫外吸收发生红移, 吸收强度下降, 但荧光发射强度提高, 这说明近紫外吸收有利于荧光发射强度的提高.

| Abstract: | Stilbene fluorescence monomer was synthesized by esterification and condensation with the main raw materials of chloromethyl benzoate, triethyl phosphate and terephthalaldehyde through Wittig-Horner reaction. Stilbene fluorescence monomer was then polymerized to produce fluorescent polymer with good water solubility, strong fluorescence, high stability and safety. The fluorescent monomer structure was characterized by infrared (IR) spectra. The fluorescence properties of fluorescent monomer and polymer were studied with a ultraviolet (UV) absorption spectrophotometer and a fluorescence spectrophotometer. It was found that, compared with fluorescence monomer, the ultraviolet absorption peak of fluorescence polymer was red drifted with the absorption intensity lowered, but the fluorescence emission intensity was increased, meaning that near ultraviolet absorption is in favor of the increase of fluorescence emission intensity. |
