摘要：

A facile synthesis of previously Unknown, well-separated, uniform chiral microstructures from achiral pi-conjugated organic Molecules was developed by simple solution process. Detailed characterization and formation mechanism were presented. By simple structure modification or temperature change, the pitch of the chiral structure can be fine tuned. Our result opens new possibilities for novel materials in which Structure chirality is coupled to device performance.
