Back Cover: On-off switching of reflection from multi-bilayered films consisting of azo-polymer liquid crystal and polyvinylalcohol was achieved by annealing and UV-irradiation. The switching is based on the difference in the refractive indices (Δn) between the polymer layers, arising from the change in the molecular orientation of azo-chromophores. Further details can be found in the article by M. Moritsugu, T. Ishikawa, T. Kawata, T. Ogata, Y. Kuwahara, and S. Kurihara* on page 1546.
