Comparison of new photorefractive composites based on a poly(phenylene vinylene) derivative with traditional poly(n-vinylcarbazole) composites
Literature Information
The performances of two classes of photorefractive polymer composites with low glass-transition temperatures (about 10–5°C) are compared. One is based on the commonly used photoconductor poly(N-vinylcarbazole) (PVK), i.e., containing isolated charge-transport moieties for hopping. The other is based on the π-conjugated poly[1,4-phenylene-1,2-di(4-benzyloxyphenyl)vinylene] (DBOP-PPV), promising faster response times. The steady-state performance of the DBOP-PPV-based composites was found to be superior owing to (i) the larger internal free volume, allowing more efficient poling of the chromophores, and (ii) the slightly stronger space-charge field as a result of an increased trap density. By contrast, the dynamic response in a four-wave mixing experiment was similar to that of PVK-based composites despite the higher hole-drift mobility in conjugated PPV homopolymers than PVK. It was demonstrated that this is mainly a result of the poor charge-carrier generation efficiency.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
