Electrochemiluminescence (ECL) is a powerful analytical tool for point-of-care testing (POCT) of diagnostic biomarkers. Organic ECL emitters based on boron-dipyrromethene (BODIPY) have been developed but rarely applied to small-molecule detection. Herein, we report three BODIPY-based probes for detection of hydrogen peroxide (H2O2), one of the reactive oxygen species, and glucose which is the typical sign of various diseases such as diabetes. The diethyl-introduced probes exhibited enhanced ECL intensity in response to H2O2, which improved the sensitivity of detection. Moreover, fluorination near the recognition site, boronate pinacol ester, accelerated the detection speed. Our ECL probe 2F proved to be effective by the sensitive and selective detection, indicating the potential application into POCT. The applicability of 2F was further assured by the real sample experiment in which glucose present in human serum was precisely quantified.
