Bis-porphyrin arrays. Part 3.†The synthesis of model bis-porphyrin dimers and an electrochemical study
Abstract
We have successfully synthesised exo and endo diphenylacetylene linked bis-porphyrin dimers. We found that the exo-bis-porphyrin dimer could be easily prepared in good yield whilst the endo-dimer was harder to form due to the steric constraints of the meso-substituents. Electrochemical studies indicated that the
