A chemosensor for the Al(3+) ion, 1-[(3-hydroxypyridin-2-ylamino)methylene]naphthalen-2(1H)-one (H2L), based on inhibited excited-state intramolecular proton transfer was synthesized. The experimental and theoretical calculations at B3LYP+PCM/6-31G(d) revealed that Al(3+) and H2L form a 1:1 complex, [AlL(OH)(H2O)]2, in dimethyl sulfoxide that exhibits two remarkably enhanced fluorescent emissions at 523 and 553 nm. It is confirmed that H2L could be used to detect Al(3+) ions in cells by bioimaging.
一种基于抑制的激发态分子内质子转移的 Al(3+)离子化学传感器，1-[(3-羟基吡啶-2-基氨基)亚甲基]萘-2(1H)-酮（H2L）被合成。在 B3LYP+PCM/6-31G(d)的实验和理论计算表明，Al(3+)和 H2L 形成了 1:1 的配合物，[AlL(OH)(H2O)]2，在二甲基亚砜中表现出两个显著增强的荧光发射峰，分别在 523nm 和 553nm。证实 H2L 可用于通过生物成像检测细胞中的 Al(3+)离子。
