Nitrosation of BODIPY dyes and their applications in the development of thiol sensors

Abstract Herein we describe a new method for the post-functionalization of BODIPY dyes, by means of nitrosation with NOBF4, in yields of up to 93%. The application of nitroso-BODIPY dyes as analytical tools for the fluorimetric analysis of thiols is also shown, including the ability to cross cell membranes.
