A novel dual-responsive fluorescent probe for the detection of copper(II) and nickel(II) based on BODIPY derivatives

Preparation of Large Conjugated Polybenzimidazole Fluorescent Materials and Their Application in Metal Ion Detection

“…Importantly, a new absorption can be observed at 1121 cm −1 when CPBI 2 interacts with Cu 2+ . It is consistent with the results in the literature [ 16 , 60 , 61 , 62 ]. In addition, the results of SEM further demonstrate that the original nanoparticle structure of CPBI 2 ( Figure 7 d) has aggregated into a massive flaky structure ( Figure 7 c) after the interaction of CPBI 2 with Cu 2+ .…”

Multi-stimuli-responsive molecular fluorescent probes for bioapplications

“…Xu et al constructed the dual-responsive probe 17 based on BODIPY derivatives, which exhibited high selectivity and sensitivity toward copper( ii ) and nickel( ii ). 86 The detection limits (DLs) for copper( ii ) and nickel( ii ) were each calculated to be as low as 0.1 μM. The binding mode of 17 with each of these metal ions is 1 : 1.…”

Fluorescent and chromogenic organic probes to detect group 10 metal ions: design strategies and sensing applications

“…To date, only a few BODIPY-based fluorescent probes can be found in the literature for selective Ni( ii ) detection. 123 The interference caused by divalent Cu( ii ) ions with Ni( ii ) is one of the main reasons for the scarcity of fluorescent Ni( ii )-responsive probes.…”

“…Song et al (in 2021) developed 125 another BODIPY-based probe 15 containing DPA chelator at 2-position for selective detection of Ni( ii ) in methanol (Fig. 10).…”
