Abstract
The present invention relates to a compound for detecting phosgene and DCP (diethyl chlorophosphate) and a composition for detecting phosgene and DCP (diethyl chlorophosphate) comprising the said compound. More precisely, the compound for detecting phosgene and DCP of the present invention can selectively detect phosgene and DCP either in the liquid phase of gas phase by detecting the changes of fluorescence and color development very quickly within a few seconds with nM sensitivity. Therefore, the compound can also be effectively used as an ingredient for the composition and kit for the detection of one or more materials selected from the group consisting of phosgene and DCP.
