The first part of this lecture will cover our efforts to harness carbenes for surface modification and polymer synthesis. Specifically, the reactivity of N-heterocyclic carbenes (NHCs) toward gold and silicon surfaces and their utility as addressable surface anchors will be discussed, with several applications in polymer chemistry and materials science highlighted. Beyond persistent carbenes like NHCs, reactive metallocarbenes will be explored in the context of gold and polymer chemistry, with a particular focus on the migratory insertion mechanistic manifold for such species.<br/>In the second part of this lecture, I will address the emerging interface between supramolecular metal-organic polyhedra (also known as metal-organic cages or MOCs) and linear and network polymer synthesis. The development of polymer metal-organic cage (polyMOC) gels, wherein the self-assembly of MOC junctions leads to gelation, will be discussed first, with an emphasis on the effects of MOCs and polymer molecular architecture on the macroscopic properties of the gels. Lastly, I will touch upon the future directions to address long-standing challenges at the interface of polymer network chemistry and topology.
