A BODIPY‐based Fluorescent Probe for Thiophenol. Issue 2 (21st December 2017) - Zhang, Dongxiang
Abstract : Thiophenol has been listed as one of the main sources of pollution. Sensitive probes for thiophenol are very significant. Herein, a BODIPY‐based fluorescent probe, named BDP, for poisonous thiophenol detection has been reported. BDP shows rapid response (15 s) and clear fluorescence enhancement (30 folds) to thiophenol in solution. The intensity of fluorescence and concentration of thiophenol have a good linear relationship. The detection limit is as low as 13.6 nmol· L −1 . BDP is stable towards pH and light radiation. Cell experiments demonstrate that BDP has good cell membrane penetrability, low cell toxicity and excellent imaging properties in living cells. Therefore, BDP has significant value on the detection of thiophenol in solution and in living cell. Abstract : A fluorescent probe, BDP, for thiophenol detection shows high selectivity, fast response, high sensitivity and excellent stability, might be applied to identification of thiophenol in cells and water samples, and has potential applications in the fields of chemistry, environment and biology.
