Nitro‐porphyrins are an important class of commercial dyes with a range of potential applications. The nitro group is known to dramatically affect the photophysics of the porphyrin, but there are few systematic investigations of the contributing factors. To address this deficiency, we present spectroscopic studies of a series of nitro‐porphyrins, accompanied by density functional theory calculations...
The supramolecular chemistry of porphyrinic systems is extraordinarily diverse because the rigid macrocycles offer a variety of topologies that can be matched to the topologies of hydrogen-bonding moieties and metal ion coordination geometries. Other modes to self-assemble multi porphyrin arrays and crystals exploit electrostatic interactions, combinations of hydrogen-bonding, and metal ion coordination...
