Electron transfer priority

Among the fundamental photophysical and photochemical processes, electron transfer has a high priority. Porphyrins and metalloporphyrins form one of the most promising series of chromophoric compounds for designing suitable redox systems as described above, since they have intense visible absorption bands and the can be varied by the substituents and the central metal ions. The redox properties are also easily regulated according to purpose. In recent intensive studies on electron transfer by various approaches from the viewpoints of theory.
