A novel colorimetric and ratiometric fluorescent probe (Cou-BPO) was readily prepared for specific detection of harmful benzoyl peroxide (BPO). The probe Cou-BPO reacted with BPO via a selective oxidation cleavage-induced cascade reaction of the pinacol phenylboronate group, which resulted in an observable colorimetric and ratiometric fluorescence response towards BPO with a fast response time (<15 min) and a low detection limit (56 nM). For practical application, facile, portable and sensitive test paper of Cou-BPO has been prepared for visual detection of BPO. Furthermore, we employed Cou-BPO as a probe to determine BPO in food samples and living cells.
一种新型的比色和比率荧光探针（Cou-BPO）被制备出来，用于特异性检测有害的过氧化苯甲酰（BPO）。探针 Cou-BPO 通过对频哪醇苯基硼酸酯基团的选择性氧化裂解引发级联反应与 BPO 反应，对 BPO 产生可观察的比色和比率荧光响应，具有快速的响应时间（<15 分钟）和低检测限（56 nM）。为了实际应用，我们制备了简便、便携和敏感的 Cou-BPO 试纸，用于 BPO 的可视化检测。此外，我们还将 Cou-BPO 用作探针来测定食品样品和活细胞中的 BPO。
