: Water-soluble poly(dithiocarbonate)s were prepared through cationic ring-opening polymerization of 5-mem-bered cyclic dithiocarbonates containing hydrophilic substituents, such as alcohol, triethyleneglycol, and morpholine. The morpholine attached monomer underwent polymerization in CF 3 CO 2 H solvent, leading to in-situ protonation of an amine moiety as a catalyst scavenger. When the prepared polymers were exposed to an aqueous copper(II) ion solution, the concentration of free copper ion was measured by UV-vis absorption spectroscopy after adding a rhodamine chemosensor. A characteristic absorption of a copper-rhodamine complex at 560 nm was weakened with polymer addition, indicating consumption of free copper ion through the formation of copper-polymer complex. The absorption intensity of 0.5 µm copper solution was reduced to 1/4 in the presence of a 200 ppm polymer.
:通过阳离子开环聚合含有亲水取代基（如醇、三乙二醇和吗啉）的 5 个单体环二硫代碳酸酯，制备了水溶性聚二硫代碳酸酯。附着吗啉的单体在 CF 3 CO 2 H 溶剂中进行聚合，导致作为催化剂清除剂的胺分子原位质子化。将制备的聚合物置于铜（II）离子水溶液中，加入罗丹明化学传感器后，用紫外可见吸收光谱法测量游离铜离子的浓度。铜-罗丹明复合物在 560 纳米波长处的特征吸收随着聚合物的加入而减弱，这表明游离铜离子通过形成铜-聚合物复合物而被消耗。在 200 ppm 的聚合物存在下，0.5 µm 铜溶液的吸收强度降低到 1/4。
