title: Spectroelectrochemical evidence for communication within a laterally-bridged dimanganese(III) bis-porphyrin.
abstract: Electronic coupling between the porphyrin units of a laterally-bridged dimanganese(III) bis-porphyrin 2 is explored using electrochemistry, spectroelectrochemistry and resonance-Raman spectroscopy. It is found that strong electronic interactions between the manganese(III) ion and the porphyrin macrocycle enhance the perturbations experienced by these bis-porphyrin systems when compared to related monomer porphyrin systems. In turn this leads to effective electronic communication between the manganese ions in the bis-porphyrin. This finding has importance in the design of molecular wires based on laterally-bridged oligo-metallo-porphyrins.
