This micro-review presents an overview of molecular materials derived from phthalocyanines which are substituted with crown ether rings. These flat disk-like molecules can self-assemble into ordered, well-defined structures with or without the aid of alkali metal ions. Highly ordered assemblies of crown ether phthalocyanines are capable of transporting electrons and ions, which is of interest for sensor applications.
