In the last 30 years coordination and supramolecular chemistry have been a source of molecular assemblies and multifunctional materials with novel properties or combination of properties. These molecular systems have also shown to be relevant in other emerging fields including molecular electronics, spintronics and quantum computing [1]. A current trend in this area is to combine these molecular systems with graphene and other 2D materials with the aim of exploring the novel properties and applications that may emerge from such combinations. Here I will illustrate this concept with some relevant examples: 1) 2D MOFs with magnetic functionalities [2, 3]; 2) hybrid smart heterostructures and robust electronic devices based on bistable spin crossover molecules interfaced with graphene and other 2D materials [4-7].
