A study of helix-sense inversion of poly(phenylacetylene) derivatives was carried out. The poly(R)-1 and poly(S)-1 undergo a helix-helix transition by response to external, chiral, and achiral interaction with small molecules. The results show that the poly-1's have a predominant one-handed helical conformation in solution, and the helix-sense undergoes a transition from one helix to another in response to external, chiral, and achiral stimuli, such as temperature, solvent, and chiral interaction with small molecules.
