The project aims to explore and develop procedures and a new class of 2D materials, namely two-dimensional coordination networks (2D MONs), original by the presence in their structure of dimethylsiloxane motifs that do not allow the development of intermolecular interactions. Thin sheets obtained, either directly by synthesis under suitable conditions or by subsequent delamination, will be characterized structurally and in terms of properties. The application potential will be evaluated for pristine materials or for easier-to-handle composites manufactured by incorporating MON nanosheets as active fillers into silicone matrices.
