要旨

Crosslinked polymers containing covalently attached functional sites with chemical structures related to those present in ILs and having macroscopic properties very similar to the ones of the corresponding bulk ILs can be advantageously applied to the preparation of gold nanoparticles (AuNPs). The size and morphology of the resulting metal nanoparticles (MNPs) can be easily modulated through a proper combination of the synthetic method used for the generation of the NPs and the structural elements of the polymer. Additionally, the resulting supported AuNPs are demonstrated to be stable for at least eight months with the vials open to the atmosphere. Several synthetic methodologies have been studied, as well as different structural parameters for the functional polymers. Those include the chemical nature (anions and cations) and loading of the ionic liquid-like fragments and the morphology of the polymeric matrix. The results obtained show the potential to prepare supported AuNPs with narrow size distributions and small diameters that can have potential interest for application in different fields.

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.
