Abstract
After the discovery of graphene with the set of properties that essentially distinguish it from other allotropes of carbon, ultrathin layered materials, classified as 2D nanomaterials, enjoy increased interest due to their unique properties. In this context, very recently 2D MOFs have become of interest, but in the crystallization process the 2D layers are stacked based on intermolecular interactions, leading to materials with increased dimensionality. In order to manifest the specific properties of a 2D material, they must be isolated individually or in multilayers with a thickness/surface ratio as low as possible, which constitutes a challenge to which solutions are sought through different approaches. The idea of the project is to design and synthesize two-dimensional metal-organic networks with extremely weak intermolecular interactions, which facilitate delamination in nanosheets. The originality and the key to success in this approach is the use of ligands containing permethylated silicon units which, through their natural exposure, shield the structure and prevent the establishment of quantifiable interactions. New ligands and their combinations will be prepared and used to coordinate different metal ions or clusters. The nanosheets as such will be evaluated, but also the effect of their incorporation in silicone matrices for the development of stimuli-sensitive materials. Their common nature creates the conditions for a good compatibility and the formation of advanced composites.
