Transition-metal catalyzed C-X, C-H and C-F functionalization
The use of model platforms for the mechanistic understanding of C-H and C-X functionalizations is a wide and long term research project that continuously unravels breakthrough mechanistic aspects that help in the comprehension of the transformations and are valuable tools for catalyst design. Focus on, cobalt, nickel, copper and gold-catalyzed transformations will be studied in selected important transformations using model C-X, C-H, C-F and C-OMe substrates. Understanding the metal redox behaviour in these transformations is key to designing improved catalysts.

Bottom-up nanographene synthesis with luminescent properties
The step-by-step synthesis of nanographene scaffolds is crucial to rationalizing the ring-fused structures with their photophysical properties. Based on the Ni-catalyzed aromatic homologation precursors, straightforward development of new nanographene scaffolds by oxidative ring fusion will expand the portfolio of unprecedented nanographene platforms with fascinating luminescent properties.
Supramolecular nanocages for chemistry in the confined space
The development of supramolecular nanocapsules and the study of their host-guest abilities allows the discovery of new chemical processes and transformations in the confined space. These include: a) fullerene purification from fullerene mixtures by selective encapsulation; b) the regioselective functionalization of entrapped C60, C70 and higher fullerenes by the supramolecular mask strategy; c) synthesis of three- and four-shell matryoshka assemblies with large-cavity nanocapsules using coronene, phosphotriangulene and others; d) host-guest chemistry with spherical diamondoids (adamantane and diamantane); e) asymmetric catalysis in the confined space by encapsulating metal-catalysts and organocatalysts.
