In the herein work we report the fine and selective control of competitive processes when submitting meso-methylBODIPYs to Vilsmeier-Haack reaction conditions. These competitive processes generate BODIPYs with opposed photophysical properties, from highly fluorescent dyes enabling laser emission, to non-fluorescent singlet-oxygen photosensitizers. The synthetic control is exerted on the basis of the structure of the starting BODIPY, as well as the electrophilic character (hard or soft) of the formylating reagent. (C) 2017 Elsevier Ltd.
