The fluorescent dye perylene-3,4,9,10-tetracarboxylic dianhydride (PBA) was immobilized onto polysulfone hollow fibers by means of a wet coating procedure. After immobilization, PBA was able to react with primary amines through a double anhydride ring opening reaction. The in situ amine coupling was further revealed by fluorescence analysis. Both emission (534 nm →538 nm) and fluorescence lifetime changes (2.7 ns →3.3 ns) of the dye are a useful tool to detect and visualize the occurrence of the reaction. The successful implementation of amine coupling with a reporting function on polysulfone fibers holds great interest for biomedical applications.

Hol-3,4,9,10-四羧酸二酐在中空聚砜纤维上的固定：伯胺偶联和荧光报告。
荧光染料procedure 3,4,9,10-四羧酸二酐（PBA）通过湿涂法固定在聚砜中空纤维上。固定后，PBA能够通过双酸酐开环反应与伯胺反应。通过荧光分析进一步揭示了原位胺偶联。染料的发射（534 nm→538 nm）和荧光寿命变化（2.7 ns→3.3 ns）都是检测和可视化反应发生的有用工具。具有报告功能的胺偶联剂在聚砜纤维上的成功实施对生物医学应用引起了极大的兴趣。
