Tetraphenylethylene–thiosemicarbazone based ultrafast, highly sensitive detection of hypochlorite in aqueous environments and dairy products

We have designed and synthesised a novel fluorescent probe with a tetraphenylethylene (TPE) scaffold as an active fluorescent unit and thiosemicarbazide (TSC) group as a recognition unit. The probe, TPE–TSC, exhibited superior selectivity towards hypochlorite (ClO−) with a low limit of detection (2....

Zusammenfassung:We have designed and synthesised a novel fluorescent probe with a tetraphenylethylene (TPE) scaffold as an active fluorescent unit and thiosemicarbazide (TSC) group as a recognition unit. The probe, TPE–TSC, exhibited superior selectivity towards hypochlorite (ClO−) with a low limit of detection (2.0 nM). It also demonstrated a turn-off response for a brief period (
