Materials-chirality: a simple motion probe of polymeric glassy and rubbery states

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The 1,1′-Binaphthyl chiral molecule is studied. The thermal racemization of this molecule occurs through rotation about the C(1)-C(1′) bond and follows strictly first order kinetics with a half-life of between 10 and 20 hrs as a function of solvent at 20°C. This racemization can be caused by heat or by irradiation, with the energy flux controlling the extent of racemization. This can be read as a gray scale of response to circularly or plane polarized light which can be read over a wide wavelength range following from the optical rotatory dispersion effect, and stored in an archival manner below Tg.
