Abstract: An aptamer-N-heterocyclic-carbene metal complex conjugate (aptamer-NHCM conjugate) or an aptamer-bis-N-heterocyclic-carbene metal complex conjugate (aptamer-bis-NHCM conjugate) includes an aptamer coupled through a hydrolytically stable bond to an N-heterocyclic-carbene metal complex (NHCM) or a bis-N-heterocyclic-carbene metal complex (bis-NHCM). The aptamer-NHCM conjugate is prepared where the chosen aptamer displays selective binding to a cell specific receptor, such that the cytotoxic NHCM can be directed specifically to cells responsible for a target disease (e.g., a specific cancer type). A method of preparing the aptamer-N-heterocyclic-carbene metal complex conjugate involves installing a coupling group to an N-heterocyclic-carbene metal complex that can specifically bond with a functional group on an aptamer; the bond, covalent or non-covalent, is stable hydrolytically in the absence of an environment that promotes intentional cleavage of the bond.

Abstract: A tetraanionic OCO pincer ligand metal-oxo-alkylidene complex is prepared from a trianionic pincer ligand supported metal-alkylidyne. The metal can be tungsten or other group 5-7 transition metal. The tetraanionic pincer ligand metal-oxo-alkylidene complex, a trianionic OCO pincer ligand metal complex, or a trianionic ONO pincer ligand metal complex can be used to polymerize cycloalkenes. The poly(cycloalkene)s are predominantly cis-alkene macrocyclics.

Abstract: Macrocyclic polyalkene homopolymers and copolymers can be formed and converted to macrocyclic polyalkanes or macrocyclic poly(alkane-co-alkene) upon hydrogenation or, when the macrocyclic polyalkene is reacted with an alkene in the presence of an olefin metathesis catalyst, to a macrocyclic poly(alkane-co-alkene) comprising vicinal —C(═CR2)—'s. Upon hydrogenation of a macrocyclic poly(alkane-co-alkene) comprising vicinal —C(═CR2)-'s, macrocyclic poly(alkane)s or poly(alkane-co-alkene)s with isolated —C(═CR2)- groups can be provided, depending on the degree of hydrogenation. The poly(alkane-co-alkene)s with isolated —C(═CR2)- units can be used to form poly(macrocyclic poly(alkane-co-alkene))s, poly(macrocyclic poly(alkane))s, and/or bi-, tri-, and/or multi-macrocyclic poly(alkane-co-alkene)s or bi-, tri-, and/or multi-macrocyclic poly(alkane)s.
