Abstract
The application discloses preparation of chiral ring-shaped nanomaterials and relates to the field of biological chiral catalytic materials. A series of chiral liquid crystal block copolymers with different polymerization degrees are prepared through grafting reaction of pentafluorophenol ester and amino biphenyl liquid crystal molecules. The method is simple and efficient, the grafting efficiency is high, and the polymerization degree of the block copolymer can be accurately controlled. The preparation of ring-shaped nanomaterials is realized by changing the proportion of hydrophilic and hydrophobic blocks of the polymer and the assembly temperature through a circulation dialysis method. The chiral signal of the chiral ring-shaped nanomaterials is controllable, which is helpful to realize high selectivity and high efficiency of chiral catalysis.
