“…, ONOO − , H 2 O 2 )-recognizing portion, with some developed fluorescent probes listed in Schemes S1–S3 (ESI†), the substituent effect has not been studied in the reported publications. 32–67 Resorufin dye possesses several advantages, including bright red emission, excellent stability, high fluorescence quantum yield, and good photostability. 68,69 Several boronate-containing resorufin probes have been reported to be able to detect tyrosinase, benzoyl peroxide (BPO), or hydrogen peroxide (H 2 O 2 ); however, the response rates were slow (10 min to 10 h, Table S1, ESI†).…”
