Abstract
Disclosed are photonic crystals containing photoresponsive molecules and a method of preparing the same. More particularly, it is possible to synthesize photonic crystals containing photoresponsive molecules that induce photoalignment of azobenzene by ultraviolet irradiation using bent-shaped liquid crystal molecules containing azobenzene, which causes photo-isomerization upon ultraviolet irradiation, form a periodic structure in a visible light region using a self-assembly phenomenon occurring as temperature decreases, realize a reflection color and enable reversible pattering.
