Highly reactive (<1 min) ratiometric “naked eye” detection of hypochlorite with real application in tap water†
Abstract
The de-diaminomaleonitrile reaction in a simple carbazole diaminomaleonitrile hybrid (CDH) was promoted by OCl− which disrupted the ICT mechanism by breaking the donor and acceptor linkage. This system utilized an irreversible OCl− promoted oxidation reaction and it responded instantaneously at room temperature. The chemosensor also showed excellent performance in tap
