本文通过高分子后功能化反应,制备出具有绿色荧光、侧链连有二(2-(乙硫基)乙基)胺基团的双取代聚乙炔P2,高分子P2对Fe3+具有高灵敏度、良好选择性的识别能力。将P2制作成试纸条,可以用于实际样品中铁离子的检测。
A bis ( 2- (ethylthio) ethyl) amine-functionalized disubstituted polyacetylene (P2) with strong green fluorescence was successfully synthesized by utilizing the postfunctional method. P2 could detect Fe3+ with high sensitivity and good selectivity. Furthermore, P2 could be put into application by test strips, making P2 a practical Fe3+ probe.
