Supramolecular Chemistry of Pyrrole-Based π-Conjugated Molecules

This article summarizes the supramolecular chemistry of pyrrole-based π-conjugated molecules, with specific focus on the work carried out by the author’s group over the last nine years. The author provides a number of examples of supramolecular assemblies and functional materials comprising pyrrole-based molecules stabilized by noncovalent interactions such as metal coordination, hydrogen bonding, π–π stacking, and van der Waals forces. In particular, pyrrole-based π-conjugated molecules showed anion-binding behavior, and formed ion-based materials, wherein positively and negatively charged species were arranged in an ordered form by combination with appropriate cations.
