Porphyrins are ubiquitous in nature and play key role in light harvesting processes in photosynthesis through absorbing light energy and transferring the energy to a reaction center. 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 three of these imidazole porphyrins
