摘要：

Peroxide-based explosives, like triacetone triperoxide (TATP), are important targets for detection because of their broad use in improvised explosives but pose challenges. We report a highly sensitive turn-on fluorescence detection for H2O2 and organic peroxides, including TATP. The detection strategy relies on oxidative deboronation to unmask H(2)Salen, which subsequently binds Zn2+ to form fluorescent Zn(Salen). Sensitivity is excellent, with detection limits below 10 nM for H2O2, TATP, and benzoyl peroxide. In addition, acid treatment is necessary to sense TATP, suggesting the potential to discriminate between H2O2 and TATP based upon minimal sample pretreatment.
