Various combinations of porphyrin ions with controlled electronic states were achieved by ion-pair metathesis based on the hard and soft acids and bases (HSAB) theory. The transient absorption spectra of the porphyrin ion pairs revealed photoinduced electron transfer from the anion to the cation through substituent-dependent photoexcitation processes.

In this paper, we developed a technique for the nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents in order to prepare meso-silyl-substituted Ni(II) porphyrins. Porphyrin silylation occurs under mild conditions and exhibits both excellent substrate generality and functional group compatibility.
