Acid Properties of Porphyrins and Related Systems

Structural, energetic, and electronic aspects of a series of porphyrins and related compounds in their neutral, anion, and dianion electronic states have been studied by means of DFT calculations [B3LYP/6-31+G(d,p)]. Analysis of the electron density puts forward a number of different kinds of interactions between the inner atoms. Intramolecular correlations similar to those found in intermolecular N-H···N interactions have been found.
