Synthesis of Bis{ meso-Tetrakis(4- N-alkylpyridiniumyl)porphyrinato}cerium and Its Redox Switching Behavior

Molecules. 2021 Feb 3;26(4):790. doi: 10.3390/molecules26040790.

Abstract

A novel double-decker porphyrin complex, bis{meso-tetrakis(4-N-alkylpyridiniumyl)porphyrinato}cerium, was prepared. Electrochemical measurements revealed that this complex exhibited reversible redox waves corresponding to a 1e- redox reaction of the cerium center. Treating the complex alternately with an oxidant and a reductant resulted in the reversible redox switching between the oxidized and reduced states in an organic solvent.

Keywords: double-decker cerium complex; octacationic complex; redox switching.
