ABSTRACT: Reaction between H2TFcP (TFcP2- is a dianion of 5,10,15,20-tetraferrocenylporphyrin) with Sn(II) chloride gave the trans-Cl2SnTFcP complex, which was characterized by UV-visible, MCD, 1H and 13C NMR, and APCI MS methods. X-ray single crystal anal. was used to det. the structure of the target compd. Crystallog. reveals a very unusual α,α,β,β-conformation of the ferrocene groups and largely planar structure of the porphyrin macrocycle. D. functional theory calcns. predict that the HOMO in trans-Cl2SnTFcP is predominantly ferrocene centered, while LUMO is primarily localized over the porphyrin core. Redox properties of the trans-Cl2SnTFcP complex were studied using electrochem. (CV and DPV), spectroelectrochem., and chem. oxidn. approaches. Electrochem. expts. conducted in low-polarity solvent using noncoordinating electrolyte reveal the sequential oxidn. of ferrocene substituents along with porphyrin-based single-electron oxidn. and redn. processes. The 1st ferrocene oxidn. process is sepd. byJournal of Porphyrins and Phthalocyanines 01/2011; 15(7-8):612-621. · 1.40 Impact Factor -
