Abstract

We test poly(4-vinylpyridine) as a new matrix polymer in photorefractive polymer composites. It has excellent compatibility with OH-derivatized electro-optical chromophores due to H-bonding. Due to the slightly higher polarity, the molecular figure-of-merit of the chromophores is enhanced, yielding improved steady-state PR performance compared with PVK-based reference materials. However, because of the H-bonding the orientational mobility of the chromophores is hindered, limiting the dynamics of grating formation.
