- Abstract
Dihydroxybenziphthalocyanine 1, with bulky aryloxy groups, has been synthesized and characterized by X-ray crystallography, NMR and UV/Vis-NIR spectroscopy, and theoretical calculations. Macrocycle 1 is the first example of an aromatic benziphthalocyanine with an 18π-electron structure, and was found to exist as an equilibrium mixture of weakly aromatic and strongly aromatic tautomers. The aromaticity and near-IR absorption can be controlled by chemical modification at the reactive resorcinol moiety and by variation of the solvent.
