Abstract

Abstract:

Formation of periodic networks by molecular building blocks in solution has been a challenge in supramolecular chemistry and self-assembly field. It has been well-established that multitopic building blocks with three or four binding sites can generate supramolecular polymers in solution driven by intermolecular noncovalent interactions. Increasing the rigidity of multitopic building blocks can enhance the preorganization of their binding sites, strengthen the cooperativity and multivalency of intermolecular non-covalent interactions, and increase the ordering or periodicity of their self-assembled architectures. This account summarizes some of the important advance in the construction of supramolecular polymers from multitopic building blocks and our effort in creating two-dimensional (2D) supramolecular organic frameworks (SOFs)-a new family of solution-phase periodic self-assembled networks.

Key words: supramolecular organic framework, supramolecular polymer, self-assembly, preorganization, aromatic stacking, hydrophobicity
