We report a new H-bond macrocyclic chromogenic chemosensor in organic media, H(3)L, which displayed drastic changes in its UV-vis spectra revealing selectivity for dihydrogenphosphate over other inorganic anions, such as acetate or fluoride. The X-ray crystal structures of the [H(4)L···NO(3)]·(CH(3)CN)(4) and [H(4)L···CF(3)CO(2)]·(CH(3)CN)(2) salt complexes are also reported.
我们在有机溶剂中报告了一种新的 H-键大环显色化学传感器 H(3)L，其紫外可见光谱发生了剧烈变化，显示出对二氢磷酸盐的选择性，而对其他无机阴离子（如乙酸盐或氟化物）则没有选择性。还报道了 [H(4)L···NO(3)]·(CH(3)CN)(4) 和 [H(4)L···CF(3)CO(2)]·(CH(3)CN)(2)盐配合物的 X 射线晶体结构。
