| Porous materials are solids with high and accessible surface areas, making them ideal candidates for applications in catalysis, adsorption, and storage and for purification purposes. Besides the well-known inorganic examples, such as porous metal oxides, zeolites, or activated carbons, new materials of entirely organic composition line up to extend the range of properties and applications of this class of materials. Triazine (Tz, C3N3) units can be joined together to form a 2D/3D van der Waals (vdW) heterostructure that is bridged by phenyl-groups (2D TzF) and by diyene-groups (3D TzG). TzF/TzG features an inherent band gap, which sets it apart from graphene-based systems as a narrow bandgap semiconductor for post-silicon electronic devices. As-synthetised, macroscopic films of 2D TzF/3D TzG heterostructures contain copper nanoparticles that are useful for C-N bond formation and as mimicks of peroxidase activity. Thermal tempering (carbonisation) further leads to more accessible surface area, and an increase in catalytic activity of these polymeric framework materials. |
