A new colorimetric and near-infrared (NIR) fluorescent chemosensor (1) for Cu(2+) based on BODIPY has been synthesized and investigated in this work. 1 Displays a high selectivity for Cu(2+) with about 250-fold enhancement in fluorescence emission intensity and micromolar sensitivity (K(d)=2.8±0.3 μM) in comparison with alkali and alkaline earth metal ions (Na(+), K(+), Mg(2+), Ca(2+)) and other metal ions (Ba(2+), Zn(2+), Cd(2+), Fe(2+), Pb(2+), Ni(2+), Co(2+), Ag(+)) upon excitation at 635 nm in CH(3)CN. Meanwhile, the distinct color changes and rapid switch-on fluorescence also provide 1 as colorimetric senor for Cu(2+).
本文合成了一种基于 BODIPY 的新型比色和近红外（NIR）荧光化学传感器（1），用于检测 Cu(2+)。与碱金属和碱土金属离子（Na(+)、K(+)、Mg(2+)、Ca(2+)）以及其他金属离子（Ba(2+)、Zn(2+)、Cd(2+)、Fe(2+)、Pb(2+)、Ni(2+)、Co(2+)、Ag(+)）相比，在 635nm 激发下，1 对 Cu(2+)具有高选择性，荧光发射强度增强约 250 倍，微摩尔灵敏度（K(d)=2.8±0.3 μM）。同时，明显的颜色变化和快速开启的荧光也使 1 成为 Cu(2+)的比色传感器。
