Abstract

A photonic polymer network was imprinted using multiple UV-induced polymerizations in the presence of cholesteric liquid crystals (CLCs). Here, the imprinted polymer matrices provided a chiral environment due to the chirality of the polymer networks. The fabricated cell exhibited Bragg reflections even in the absence of anisotropic materials. Moreover, a phototunable liquid crystal cell was fabricated with photosensitive liquid crystalline ethyl 4- ...
