Reactive mesogens (RMs) are polymerisable liquid crystals that can be formed through the process of in‐Situ photopolymerisation into thin birefringent films. These films have found applications as optical films (retarders) in the flat panel display industry. Application of the birefringent films requires homogeneous orientation of the optical axis over the film's surface. We report high quality fast photoalignment of reactive mesogens on surfaces of cellulose‐cinnamate polymers. Unique photosensitivity of cellulose‐cinnamates and high quality photo‐orientation of reactive mesogenes on these polymers allow cellulose‐cinnamates to be considered as promising materials for producing thin birefringent polymer films by roll‐to‐roll technology.
