Coordination-driven self-assembly of PEO-functionalized perylene bisimides: supramolecular diversity from a limited set of molecular building blocks.

A limited number of poly(ethylene oxide)-substituted perylene bisimides, some of which are equipped with terpyridine ligands for transition-metal coordination (see structure), combine different types of noncovalent interactions to yield optoelectronically active organic materials with different types of supramolecular morphologies.
