A new colorimetric molecular sensor allowing for cheap, fast, sensitive, and highly selective naked-eye detection of Hg(2+) in water is described. This molecule combines a 1,8-diaminoanthraquinone signaling subunit and phosphonic acid esters that confer the water solubility to the dye (R = H). A ready-to-use colorimetric solid sensor was obtained by incorporating an amphiphilic analog (R = OC(12)H(25)) exhibiting similar binding properties and optical responses in an agarose film.
描述了一种新的比色分子传感器，可用于在水中廉价、快速、灵敏且高度选择性地进行肉眼检测 Hg(2+)。该分子结合了 1,8-二氨基蒽醌信号亚基和膦酸酯，使染料具有水溶性（R = H）。通过将具有相似结合特性和光学响应的两亲性类似物（R = OC(12)H(25)）掺入琼脂糖膜中，获得了一种即用型比色固态传感器。
