In recent years, azo polymers have attracted increasing attention because of their potential uses in various photonic applications. Ideal materials for optical switching and image storage should possess a large induced birefringence, high writing-erasing rate, long term stability and high sensitivity. Even polymers containing azo moieties can fulfill those requirements, to achieve a good performance in practical applications, further improvement must be done towards these objectives. In this work, the azobenzene units are introduced as photoalignment triggers with good optical response and the organic crystals provide large birefringence, a high order parameter and good stability of the aligned state.
