Creation of chiral macromolecules with self-replicating and improving abilities

Alkylsilane dendrimers with multi-functionalities of asymmetric autocatalysis were synthesized by the coupling reaction between the dendritic core and pyrimidine moieties. It was found that the chiral dendritic macromolecules possess the ability of the asymmetric autocatalytic self-replication and self-improvement. In addition, the discrimination of cryptochirality of isotactic polystyrene has been achieved in conjunction with asymmetric autocatalysis.
