Inverse Chirality Probe in Poly(3-alkylthiophene) Derivative

The preparation and study of a new poly(3-alkyloxythiophene)--bearing a chiral center--is presented, with particular reference to the evolution of optical activity in passing from solution to solid state. The combination of optical analysis, electronic circular dichroism, and X-ray diffraction of powders or fi lms supplies strong indications of a possible use of this material as an inverse chiral probe.
