Synthesis of Materials with Nanostructured Periodicity

Abstract

This chapter reviews main‐chain‐ and side‐chain‐functionalized supramolecular polymers that were synthesized by ring‐opening metathesis polymerization (ROMP) and acyclic diene metathesis (ADMET) polymerization. The polymers are assembled using directional supramolecular interactions, such as H‐bonding, M–L coordination, and inclusion complexation, or a combination thereof. Supramolecular main‐chain polymers can be formed using several methods. The simplest way is using a single type of monomer containing groups that can homo‐dimerize. Side‐chain‐functionalized supramolecular polymers via olefin metathesis have emerged as modular targets, owing to the ability of metathesis to install a variety of desirable functional groups. Self‐complementary H‐bonding motifs have been utilized to form supramolecular polymers. Multifunctional supramolecular block copolymers have been prepared from the self‐assembly of two end‐group‐ and side‐chain‐functionalized polymers. Comprehending the self‐assembly behavior of polyrotaxanes and exploiting noncovalent interactions can lead to the integration of internal motion (for example, translation, rotation, scissor‐like motion) within supramolecular polymer frameworks.
