摘　　要：Self-assembly of chiral amphiphiles with π-conjugated tectons into one-dimensional helical nanostructures offers great potential applications in the biological,physical,and material sciences.In this review,the recent development of supramolecular self-assembly of chiral amphiphiles with π-conjugated tectons has been discussed on the basis of experimental exploration by elegantly utilizing cooperative noncovalent forces such as π-π stacking,hydrophobic interaction,hydrogen bond and electrostatic interaction,and the potential applications of these self-assembled helical nanostructures in chiral recognition,asymmetric catalysis,electrical conduction,switchable interfaces and soft template for the fabrication of one-dimensional hard materials are described by a representative example.Meanwhile,some scientific and technical challenges in the development of supramolecular self-assembly of chiral amphiphiles with π-conjugated tectons are also presented.It is hoped that this review can summarize the strategies for self-assembling soft nanomaterials by using chiral amphiphiles with π-conjugated tectons,and also as a guideline for design functional nanomaterials for various potential applications.Self-assembly of chiral amphiphiles with π-conjugated tectons into one-dimensional helical nanostructures offers great potential applications in the biological, physical, and material sciences.
