Adv Mater

January 2025

Polymer Performance Materials Group, Department of Chemical Engineering and Chemistry and Institute for Complex Molecular Systems (ICMS), Eindhoven University of Technology, Eindhoven, 5600 MB, The Netherlands.

Organic aerogels are an advanced class of materials renowned for their ultralow thermal conductivity and highly porous architecture, making them ideal for applications in thermal insulation, catalysis, and chemical absorption. However, these polymeric networks pose environmental concerns as their permanently crosslinked scaffold makes recycling back to the original monomers virtually impossible. To tackle this issue and develop next-generation organic aerogel, a set of polyhexahydrotriazine (PHT) aerogels specifically designed for closed-loop chemical recycling are prepared.

Nanoscale

November 2024

Institut des Sciences Chimiques de Rennes, Univ Rennes, UMR CNRS 6226, Campus de Beaulieu, 35042 Rennes Cedex, France.

Article Synopsis
  • Researchers explored how to manipulate chiroptical properties in bulk materials by altering the formation of chiral nanostructures using oligodimethylsiloxane-helicene-pyrene molecules with different lengths of DMS.
  • They discovered that in bulk, these materials self-assemble into 2D structures due to phase segregation, leading to significant differences in properties between racemic (mixed) and enantiopure (pure) forms, as well as a substantial increase in circularly polarized luminescence compared to solution state.
  • The findings indicate that tailoring the length of DMS chains influences the emission characteristics, paving the way for new uses in optoelectronics and communication technologies by blending chiroptical materials

Microgels show advantages over bulk hydrogels due to convenient control over microgel size and composition, and the ability to use microgels to modularly construct larger hierarchical scaffold hydrogel materials. Here, supramolecular chemistry is used to formulate supramolecular polymer, dynamic microgels solely held together by non-covalent interactions. Four-fold hydrogen bonding ureido-pyrimidinone (UPy) monomers with different functionalities are applied to precisely tune microgel properties in a modular way, via variations in monomer concentration, bifunctional crosslinker ratio, and the incorporation of supramolecular dyes and peptides.
