Electronic delocalization in the radical cations of porphyrin oligomer molecular wires

Abstract:

The radical cations of a family of π-conjugated porphyrin arrays have been investigated: linear chains of N = 1-6 porphyrins, a 6-porphyrin nanoring and a 12-porphyrin nanotube. The radical cations were generated in solution by chemical and electrochemical oxidation, and probed by vis-NIR-IR and EPR spectroscopies. The cations exhibit strong NIR bands at ~1000 nm and 2000-5000 nm which shift to longer wavelength with increasing oligomer length. Analysis of the NIR and IR spectra indicates tha...
