In the present paper, new functionalized UiO-67 metal–organic frameworks (MOF) which contain aromatic tagged groups such as phenyl, naphthyl, and anthracene have been synthesized, characterized, and used for sensing water-soluble amino acids. The results show that anthracene-tagged UiO-67-MOF is shown to act as a highly efficient and selective aqueous sensor for arginine over other water-soluble amino acids in nanoscale. Upon adding an increasing amount of arginine, PL bands of the anth-UiO-67 MOF quenched completely, while there is no perturbation in the PL bands for other amino acid observed. This MOF allows a selective ratiometric detection of arginine without any interference from other amino acids.

蒽标记的UiO-67-MOF作为用于精氨酸氨基酸纳米检测的高选择性水溶液传感器。

在本文中，已经合成，表征并用于检测水溶性氨基酸的新型功能化UiO-67金属有机骨架（MOF）包含芳香族标记基团，例如苯基，萘基和蒽。结果表明，蒽标记的UiO-67-MOF被证明是精氨酸比其他纳米级水溶性氨基酸更高效和选择性的水传感器。加入增加量的精氨酸后，anth-UiO-67 MOF的PL带完全被淬灭，而其他氨基酸的PL带中没有扰动。该MOF可以选择性地按比例检测精氨酸，而不受其他氨基酸的干扰。
