Oligomers and macrocycles with [m]pyridine[n]pyrrole (m + n ≥ 3) domains: Formation and applications of anion, guest molecule and metal ion complexes

This review provides comprehensive coverage of larger [m]pyridine[n]pyrrole oligomeric (m + n > 3) chains or [m]pyridine[n]pyrrole (m + n ≥ 3) macrocycles with at least three directly linked heterocyclic rings, their syntheses and the complexes they form with anions, guest molecules and metal cations. Their applications found to date are summarised and future prospects are considered.
