Porphyrins and their metallic complexes have many particular properties

and they have been widely used as models of cytochrome P-450

oxidation catalysts

chemical electrodes and special functional materials etc..When supported with SiO

2

or montmorillonite or organic polymers

the porphyrins or their metallic complexes are compartmentalized

and exhibit better oxidation resistance.This paper reviews the new developments of synthesis and properties of polymer-supported porphyrins and their metallic complexes

especially as models of cytochrome P-450

photobactericidal materials

anion carriers

sensitization and electron transfer materials and so on.
