A rhodamine-deoxylactam based sensor for chromo-fluorogenic detection of nerve agent simulant

N-(rhodamine B)-deoxylactam-5-amino-1-pentanol (dRB-APOH) was designed and prepared as the chromo-fluorogenic sensor for detection of a nerve agent simulant via analyte triggered tandem phosphorylation and opening of the intramolecular deoxylactam. The successful detection of diethyl chlorophosphate suggests the utility of rhodamine-deoxylactams as the chromo-fluorogenic signal reporting platform for design of sensors targeting reactive chemical species via various chemistries.

N-(rhodamine B)-deoxylactam-5-amino-1-pentanol (dRB-APOH) was designed and prepared as the chromogenic and fluorogenic chemodosimerter for detection of a nerve agent simulant via analyte triggered tandem phosphorylation and opening of the intramolecualr deoxylactam.Figure optionsDownload as PowerPoint slide
