| Summary: | 碩士 === 國立暨南國際大學 === 應用化學系 === 107 === In this study, a series of six-membered ring-substituted porphyrins and metalloporphyrins were synthesized and the factors influencing their oxidation potential were also been investigated by electrochemical method. The different six-membered ring substituents have the inductive or resonance effects with the porphyrin ring. The main reason is that when porphyrin ring was oxidized, the porphyrin rings are deformed and these deformations directly affect the substituents with the porphyrin of the degree of resonance, thus affecting the redox potentials of porphyrin.
In the electrochemical result, the different electrolytes impact the oxidation potentials of porphyrin.The main reason is that if the electrolyte contain big size anion, in the oxidation part, it will effect the electron transfer between porphyrin and electrode surface.
