The synthesis of metal-containing tetrapyrazinoporphyrazines (azaphthalocyanines) bearing eight bulky substituents at the peripheral positions is described. The key precursor was prepared using a nucleophilic aromatic substitution reaction between a sterically hindered phenol and 5,6-dichloropyrazine-2,3-dicarbonitrile. Thus, azaphthalocyanine (AzaPc) derived from 2,6-isopropyl-4-nitrophenol possesses substituents that are forced by steric constraints to adopt a non-planar conformation which drastically enhances the solubility of the macrocycles and inhibits efficient cofacial interaction of the macrocycles even in the solid state as evaluated by UV-visible and 1H NMR spectroscopic techniques. The intense absorption in the red visible region and photostability of these highly soluble and non-aggregated complexes enhance the dynamic activity and make these complexes potentially suitable for PDT.
