Selective DCP detection with xanthene derivatives by carbonyl phosphorylation†
Abstract
Rhodamine derivatives (1–2) exhibited dual channel ‘turn-on’ photophysical signalling selectively with diethyl chlorophosphate (DCP) among various organophosphates (OPs), where the spiro-ring opening corresponds to the adduct formation through phosphorylation at their carbonyl O-spiro nucleophilic centres.
