要旨

Fe3O4 (magnetite) nanocrystals with an average size of 13 nm were prepared using a specially synthesized polymeric stabilizer (poly-4-vinylpyridine-co-acrylamidoethylamine-co-polyethyleneglycol-co-polyethyleneglycolic acid) that bears reactive groups for further functionalization. The polymer shell made the nanocrystals amphiphilic, i.e. they are soluble in pentanol, water and dichloromethane, and they distribute over the three solvents in a three phase system. The Fe3O4 nanocrystals exhibited the well-known and typical magnetic properties.

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.
