So-called hyper-structure photorefractive molecules are covalently linked to different photorefractive functional components necessary to realize the photorefractive effect.Its well known that carbazole methine groups not only possess the ability to transport electron but also play the roles of photogeneration.[1] In this article,hyperstructured photorefractive molecules(CRA-CzCSN)was prepared by the esterification reaction between CRA-COCl and hydroxyl group-containing methine chromophore(CzCSN).
