我们报道了一种新的氢键大环显色化学传感器H（3）L，它在有机介质中显示出其紫外-可见光谱的剧烈变化，显示出对磷酸二氢根的选择性超过其他无机阴离子，如乙酸根或氟离子。本文还报道了[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。
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.
