Abstract :

Chirality is deeply embedded in the intricate processes of nature. Less explored is the influence chirality has on the properties of synthetic materials. Asymmetry�s impact is typically minor when dealing with random coil materials but becomes an overarching driver on the properties of polymers that adopt defined structures. Helical chains are the focus herein. Carbodiimides are a unique class of monomers that can be polymerized using transition metal catalysts to yield conformationally-stable helical polymers. By up fitting the metal centers with chiral ligands polycarbodiimides having a preferred screw-sense can be formed. These optically active polymers show highly unusual optical switching, self-assembly, surface, and bulk phase vapor sensing properties. The preparation and properties of chiral polycarbodiimides will be discussed.
