Chiral micelles have been drawing
ever-increasing attention because
of their potentials in mimicking the unique stereochemical effects
of enzymes. This article reports on the first success in preparing
chiral micelles through self-assembly of helical polyacetylene bearing
cholic acid pendants. The micelles were further used as chiral nanoreactor,
in which achiral acetylenic monomer smoothly underwent helix-sense-selective
polymerization (HSSP). The HSSPs directly established optically active
core/shell nanoparticles whose shell and core both were constructed
by helical polymers. The shells (or micelles) provided a protective
effect for the preferably induced one-handed helical polymer chains
in the cores. The present work provides insights into the self-assembly
of chiral helical polymers, and also provides a powerful strategy
for constructing novel chiral polymer nanoarchitectures
