A âclick reactionâ is used to synthesise a fluorescent self-assembled monolayer, which can be used to detect Hg2+ in both water and organic solutions. The resulting fluorescence sensor exhibits a rapid response and high sensitivity to Hg2+ due to the synergy effect between the nitrogens of a triazole group and a rhodamine moiety. The sensing properties are stable over a wide pH range in aqueous solutions.
利用 "点击反应 "合成了一种荧光自组装单层,可用于检测水和有机溶液中的 Hg2+。由于三唑基团的硝基与罗丹明分子之间的协同效应,由此产生的荧光传感器对 Hg2+ 具有快速响应和高灵敏度。其传感特性在水溶液的广泛 pH 值范围内都很稳定。
