Our research interests lie in the formation of porphyrin arrays through novel binding modes to metal centers. We have recently synthesized and characterized a series of porphyrins with imidazole groups incorporated onto the porphyrin periphery. The imidazole ring affords two binding sites, with one nitrogen bonded to the porphyrin, the other one can act as a Lewis base to coordinate to metal centers. The other binding site comes from the formation of an imidazolium group and the formation of the N-heterocyclic carbene. This will allow the carbon atom between the nitrogens to coordinate to a metal center. We will describe the formation and the electronic properties of these imidazole porphyrins.
