Synthesis and Self-Assembly of Difunctional Halogen-Bonding Molecules:A New Family of Supramolecular Liquid-Crystalline Polymers

摘要

Supramolecular polymers,defined as arrays of small molecules held together via noncovalent bonds,have a great potential to act as specific functional materials because of their dynamic and reversible characteristics compared to traditional polymers.The noncovalent interactions include hydrogen bonding,pi-pi interaction,hydrophobic interaction,C-H-pi interaction,donor-acceptor interaction,and metal ion coordination,etc.During the past decade,research has been directed toward hydrogen-bonded Supramolecular liquid-crystalline materials.
