Chemical and biological sensing using 2-D nanomaterials has been an area of intense investigation including inorganic materials that exhibit high sensitivity, however it has been limited as a field due to the lack of selectivity among analytes. While 2D inorganic materials can readily decipher between donor/acceptor groups, strategies to incorporate selectivity in these devices is crucial. Organic 2D materials known as covalent organic frameworks are large porous and repeated organic frameworks which have been shown to act as selectivity agents due to functionalization and porosity. This research focuses on the association of COFs with 2-D nanomaterials using top-down microwave-assisted activation of TMDs and deposition of COF particles creating TMD-COF Heterostructures. Several known COF species have been examined in order to understand the fundamental surface interactions between 2-D nanomaterials and COFs Kinetics and mechanistic studies were used to determine the manner of association of the inorganic and organic substrates.
