Abstract
Photonic crystals have attracted great attention because of their potential applications in optical materials. When an optically birefringent liquid crystal is incorporated in photonic crystals, structural coloration can be easily changed by external stimuli, such as electric field, annealing and light irradiation. In this review, our recent work on the phototunability of photonic crystals consisting of azobenzene-containing polymers is discussed, and their birefringence properties based on their polymeric molecular structures are reviewed.
