Abstract:
The synthesis of an isoamethyrin-type expanded porphyrin bearing both meso- and β-substituents is presented. The diprotonated form of this macrocycle was characterized by conventional spectroscopic means and via a single crystal X-ray diffraction analysis. This species is observed to adopt a planar conformation in the solid state. Nonetheless, the inner ring current, as inferred from 1 H NMR spectroscopic studies, is found to be severely diminished as compared to isoamethyrin, by the presence of the two meso-phenyl moieties. A second crystal structure, in which a molecule of water is hydrogen-bound to a pyrrole NH , was also solved.
