The synthesis and quenching behavior of a series of water‐soluble, carboxylate‐carrying phenyleneethynylene oligomers—monomer to tetramer—and their polymers are reported; their quenching behavior with different test analytes (paraquat, lead salts, mercury salts, picric acid, methylpyridinium iodide) in water were investigated, and the results were compared to that of the conjugated polymer. Significant
报道了一系列水溶性的,携带羧酸盐的亚苯基亚乙炔基低聚物(对四聚体的单体)及其聚合物的合成和猝灭行为;研究了它们在水中的不同测试分析物(百草枯,铅盐,汞盐,苦味酸,甲基吡啶碘化物)的猝灭行为,并将结果与共轭聚合物进行了比较。发现了显着但依赖分析物的增强作用。对于单价淬灭剂,仅适用分子键效应,但对于二价淬灭剂,多价效应也很重要。
