HYPER-STRUCTURED PHOTOREFRACTIVE MOLECULES USING CALIX4- RESORCINARENE AS CORE CONTAINING CARBAZOLE METHINE

摘要

So-called hyper-structure photorefractive molecules are covalently linked to different photorefractive functional components necessary to realize the photorefractive effect. It's well known that carbazole methine groups not only possess the ability to transport electron but also play the roles of photogeneration. In this article, hyper-structured photorefractive molecules (CRA-CzCSN) was prepared by the esterification reaction between CRA-COCl and hydroxyl group-containing methine chromophore (CzCSN). The resultant CRA-CzCSN was characterized by ~1H-NMR, FT-IR, UV-vis, GPC and DSC. CRA-CzCSN showed good solubility in common solvents such as THF, CHCl_3.
