含荧光素功能基丙烯酸酯共聚物的合成与表征

摘要

A novel method to fabricate fluorescent polymer ( F -CPA ) was reported based on the esterification between acrylate copolymer ( CPA ) and fluorescein using N , N -dicyclohexylcarbodiimide ( DCC )/4 -dimethylaminopyridine (DMAP) as catalyst.The resulting copolymer was characterized by fourier transform -infrared spectroscopy ( FT -IR ) , gel permeation chromatography ( GPC ) , differential scanning calorimetry ( DSC ) , thermogravimetric analysis ( TGA) , ultraviolet-visible spectroscopy ( UV-Vis) and fluorescence spectroscopy.%以N，N-二环己基碳酰亚胺（ DCC）和4-二甲氨基吡啶（ DMAP）为酯化反应的催化剂，使丙烯酸酯共聚物（ CPA）和荧光素进行酯化反应，得到一种新型荧光聚合物（ F-CPA）。通过傅里叶红外光谱（ FT-IR）、差示扫描量热法（ DSC）、凝胶色谱法（ GPC）、热失重分析（ TG）、紫外可见光谱（ UV-Vis）和荧光光谱（ PL）对F-CPA进行了表征。
