The utilization of N-heterocyclic carbenes (NHCs) as ligands has substantially modified the scope and application of transition metals in a variety of areas.1 Advantageous effects have been, in parts, attributed to the strong metal-carbon bond in NHC complexes, which originate from a relatively high covalent contribution to the overall bonding.2 In addition, NHC ligand design is most versatile, enabling an enormous synthetic variability. As a consequence, NHCs have been combined with a range of other privileged ligand classes in attempts to foster synergies, including for example bipyridine-type scaffolds, phosphine NHC hybrids, and pincer platforms. We will discuss some of our endeavours in combining versatile NHC metal active sites with orthogonal functionalities, including for example biochemical scaffolds, inorganic and polymeric supports, and photochemically active entities.3
