Phthalocyanine aggregates, hydrogen-bonde

In addition to axial coordination, hydrogen bonding is another important approach to construct various supramolecular systems. This strategy, however, has not been widely used to assemble phthalocyanines and other functional units. To our knowledge, examples are so far confined to several phthalocyanine-fullerene arrays and self-assembled phthalocyanine aggregates, which are described in this section.
