| 摘 要： | 以季戊四醇为"中心核",与1,2,4-偏苯三酸酐和环氧氯丙烷反应合成超支化聚合物,利用合成聚合物分子外围的羧基与2-(4-羧基苯基-)苯并口恶唑改性乙二醇二缩水甘油醚反应,得到超支化荧光聚合物。通过TG、红外光谱和荧光光谱等手段表征了合成聚合物的热稳定性,及结构与荧光性能的关系。将2-(4-羧基苯基-)苯并口恶唑结构引入超支化聚合物分子外围,其发射光谱的峰值由568 nm紫移至528nm,同时荧光强度增强。

| Abstract: | Hyperbrunched polymer was synthesized from pentaerythritol(as the central core),1,2,4-trimellitic anhydride and epichlorohydrin,by using the peripheral carboxyls of the synthesized polymer molecules and ethylene glycol diglycidyl ether which have been changed the properties by 2-(4-carboxyl benzyl group-)benzoxazole reacting together,the hyperbrunchedr fluorescent polymer was formed.The stabilization of the synthesized polymer and the relation of structure and fluorescent function were indicated by TG,infra-red spectrometry and fluorescent spectroscopy.After the 2-(4-carboxyl benzyl group-)benzoxazole being comformed to the outside of the hyperbrunched polymer molecules,the peak value of emission spectra was turned to 528 nm from 568 nm and the fluorescent has been intensified. |
