摘要: Cyclic voltammetry and thin-layer spectroelectrochemical properties of the free base 5,10,15,20-tetrakis(1,3-benzodioxole)porphyrin (H2P), its manganese iron complexes (MnP FeP, respectively) were studied in dichloromethane with tetra-butyl ammonium hexafluorophosphate (TBAPF6) as supporting electrolyte. The undergoes two monoelectronic oxidations at +0.71 +0.96 V vs. Ag/Ag+, corresponding to formations π-cation radical dication. Two reductions observed -1.53 -1.87 formation π-anion dianion species. cyclic voltammograms MnIII FeIII also showed a reversible process centered metal ion E1/2 values -0.61 -0.59 V, respectively. In typical experiment, situ response decrease Soret band 422 nm, red shift Q-bands, new low intensity bands between 800–950 nm range. Structural features spectroscopic assignments proposed ...
