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.
