A methodology for the incorporation of fluoroaryl groups into boron dipyrrinato complexes (modified BODIPY dyes) is reported. Two hexaalkylated dipyrrinato ligands with either H or CH3 occupying the meso position were employed; when they were treated with fluoroaryl haloboranes in the presence of a weak base, the title compounds were prepared in good to excellent yields. The structures of seven derivatives were determined using X-ray crystallography, and their spectroscopic, photophysical, and redox properties are compared.
