Molecular self-assembly has recently developed to create a variety of three-dimensional giant architectures, being reminiscent of large biomolecules. Coordination-driven self-assembly, particularly, is one of the sophisticated approaches to build up brilliant structures with remarkable chemical and physical properties, owing to the moderate reversibility and high directionality of the coordination bonds toward a formation of a defined structure. In contrast to the rich examples of the metal–ligand assemblies, supramolecular complexes based on noncovalent interactions have been less explored. In this paper, our recent results on molecular assemblies using a hydrogen-bonding organic host and coordination complexes are summarized. The components were strongly bound each other by concerted effects of noncovalent interactions, forming unique host–guest complexes. Thanks to the high flexibility and adaptivity of the driving forces, the self-assembled product gained remarkable complexity and functionality. The molecular assembly of the organic hosts and coordination complexes via heterogeneous conditions also afforded supramolecular structures in “out-of-equilibrium” state. These findings based on this molecular system will endow us with a chance to encounter many serendipities and provide useful materials originating from the unique structures.
