Cu (II) ion has potential roles in a lot of living metabolisms that its detection and removal are extremely important for flagship branches of science. In this paper, fluorescent and easy-make silica gel immobilized BODIPY were successfully prepared via a simple synthesis procedure for the rapid recognition of Cu (II) ions. The optimal emission and excitation wavelength of the synthesized hybrid material, Si-APTMS-BODIPY, was 543 nm and 460 nm, respectively. The new solid support surface fully characterized by several techniques has notable results and visual data for the detection of Cu (II) ion. The maximum fluorescent intensity of Si-APTMS-BODIPY was clearly quenched following the adding of Cu (II) ion owing to static and dynamic quenching mechanisms. Maybe, more importantly, there was a notable linear correlation between several concentrations of Cu (II) solution and the fluorescence quenching processes with a limit of detection (LOD) of 1.7 μ M. Based on these, a fluorescent hybrid material having high selectivity and sensitivity was made up, and it provides a precious proposal for the recognition of Cu (II) ions.
