Direct oxidation using molecularoxygen is both attractive and atom-efficient. However, this process first requires the catalyst-based activation or electronic reconfiguration of inert O2. The most expedient strategy relies on the generation of singletoxygen (1O2; a1Δg) from the triplet state (3O2; X3Σg–) by a photosensitizer. In the current arsenal of photosensitizers, boron-dipyrromethene (BODIPY)

A series of mono- to hexachlorinated BODIPYdyes have been prepared in good to excellent yields through the use of N-chlorosuccinimide as an inexpensive halogenating reagent. This library of chlorinated dyes allowed analysis in detail, from the experimental and theoretical points of view, of the dependency of the photophysical and optical properties of the dyes on the number and positions of the chlorine
