The controlled organization of individual molecules and nanostructures with nanoscale accuracy is key for the investigation of nanoscale and single-molecule events in optoelectronic, biosensing and biomimicking platforms. In this regard, we developed different strategies based on the selective functionalization of 0 dimensional (D; Quantum Dots), 1D (carbon nanotubes) and 2D (MoS2) based mixed-dimensional heterostructures towards the development of novel hybrids for single-molecule studies and different technological applications, from photo-responsive devices to nanoscale biosensing chips. We further employ DNA nanostructures as static and dynamic building blocks for the construction of the aforementioned functional nanohybrids, and for the fabrication of biomimetic nanoarrays that permit the multivalent investigation of ligand−receptor molecule interactions in cancer, with nanoscale spatial resolution and single-molecule control.

In 2007, a new class of carbenes, namely cyclic (alkyl) (amino) carbenes (CAACs), emerged as a competitor to NHCs as ligands for olefin metathesis catalysts. Since then, CAACs have been intensively studied, demonstrating exceptional productivity in ethenolysis processes (Turnover number up to 2.6 million at 100 ppb catalyst loading) while achieving remarkable catalytic performances in a number of other metathesis transformations. Despite these impressive results, the use of CAAC ligands in asymmetric catalysis is still in its infancy. This lecture will present pioneering developments in optically pure CAAC-Ruthenium complexes and their evaluation in asymmetric olefin metathesis. Additionally, thanks to density functional theory models, mechanistic insights highlighting the origin of enantioselectivity will also be discussed.
