Perylene bisimide derivatives as innovative sensitizers for photorefractive composites

摘要

In photorefractive composites, we replace the commonly used fullerene derivative phenyl-C61-butyric acid methylester (PCBM) by the perylene bisimide dimer DiPBI. In samples, wherein poly-n-vinylcarbazole (PVK) is thecharge transporting agent and 4-cyano-4
