In this work, a new fluorescent sensor, M201-DPA, based on helicene derivative was synthesized and used for the determination of Cu2+. M201-DPA revealed the selective ON-OFF fluorescence quenching at 524 nm toward Cu2+ in buffer pH 7.0 medium. The sensor was also employed as a reagent in flow injection analysis (FIA) system for online fluorescence detection of Cu2+. Precision of the method was 1.06% RSD with a sample throughput of 70 samples h−1. Low detection limit of 8.41 umol L-1 was achieved. Application of our method for analysis of Cu2+ in food supplements was discussed.
