Antenna functions of 5,15-bis(imidazol-4-yl)-10,20-bis(4-dodecyloxyphenyl)-porphyrin supramolecular assembly through imidazole-imidazole hydrogen bonding

The title bis(imidazol-4-yl)porphyrin 1 gave supramolecular assemblies through hydrogen bonding; efficient excited energy transfer followed by electron transfer to quenchers has been observed in toluene.
