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

Herein the enantio-selective polymerization of diacetylene (DA) units in the discotic hydrogen-bonding complex is carried out in an asymmetric reaction field consisting of the lamellar columnar LC phase and CPUL stimulus.
