A simple strategy for constructing PET fluorescent probe and its application in hypochlorite detection

Abstract It is great meaningful to develop a fast and efficient method for detecting hypochlorite (ClO–) owing to its importance in the immune system. In this work, we proposed a strategy to construct fluorescent probes for ClO– based on photoinduced electron transfer (PET) mechanism. According to the strategy, we developed four fluorescent probes named TPA–NO2, TPA–2NO2, TPB–NO2 and TPB–2NO2, and studied their detecting performances for hypochlorite. Among them, TPB–NO2 displayed the most obvious fluorescence changes towards ClO– with a rapid response (
