Boron difluoride adducts of diamidodipyrromethenes have been synthesized and characterized. The compounds represent a new group of the BODIPY family of fluorescent dyes. X-ray crystallography and solution 19F NMR experiments show that a persistent hydrogen bond is formed between the boron-bound fluoride groups and the peripheral amide substituents. The modular synthesis of these compounds and their robust photophysical properties suggest that they may be useful compounds for materials and biological photochemical applications.
