Abstract

Poly(pyridine–pyrrole) foldamers were designed, synthesized and characterized. X-ray diffraction analyses revealed that two water molecules were encapsulated by the foldamer possessing quasi-hydrophilic terminal groups. Both the oxygen–oxygen distance and the O–H⋯O angle indicated that there was no effective hydrogen bonding between the two trapped water molecules.
