Abstract
Circularly polarized light (CPL), regarded as a true chiral entity, has been suggested as one possible origin of the homochirality in nature. It still remained difficult to understand the exact mechanism of chiral induction, transfer and amplification in supramolecular assemblies. Herein, we designed and synthesized three discotic diacetylene LC monomer, in which the periphery diacetylene flexible chains linked to the triazole derivatives cores though H-bonding or covalent bonds. We established links between the primary chemical structures of discotic diacetylene monomer, liquid crystals phase structures and optical active properties in final supramolecular assemblies. Moreover, the type of the junction bonding interactions exhibited a significant influence on the chiral transfer in supramolecular columnar LC system.
