Intriguing Physical and Chemical Properties of Phosphorus Corroles

The fluorescence intensity of phosphorus corroles increases upon meso-aryl C–F/C–H and P–OH/P–F substitutions, the latter affects corrole-centered redox processes more than C–H/C–F substitution on the corrole’s skeleton, and the presence of F atoms allows for the first experimental insight into the electronic structures of oxidized corroles. Experimental and theoretical methodologies reveal that mono- but not bis-chlorosulfonation of the corrole skeleton is under kinetic control. Selective introduction of heavy atoms leads to complexes that are phosphorescent at room temperature.
