Patent ID: 8512534

Claim:
A polymeric transition metal complex comprising: a transition metal complex comprising the formula: wherein M is a transition metal; L 1 is a ligand comprising a heterocycle and is coordinatively bound to M via a heteroatom of the heterocycle; L 2 , L 3 , L 4 , L 5 , and L 6 are ligands comprising a nitrogen-containing heterocycle, wherein each of L 1 , L 2 , L 3 , L 4 , L 5 , and L 6 is independently a monodentate ligand or is combined with at least one other ligand to form a multidentate ligand; and wherein at least one of L 1 , L 2 , L 3 , L 4 , L 5 , and L 6 is covalently coupled to the at least one spacer; a polymer backbone; and at least one spacer covalently coupled to the polymer backbone, the at least one spacer comprising at least one non-cyclic functional group selected from the group consisting of —(CR r R s )—, —O—, —S—, —C(O)O—, —S(O) 2 NR k —, —OC(O)NR m —, —OC(S)NR n , —C(O)NR′—, —CR v ═N—O—, —CR w ═NNR x —, and —(SiR y R z )—, and wherein R r and R s are independently hydrogen, chlorine, fluorine, or substituted or unsubstituted alkyl, alkoxy, alkenyl, or alkynyl, and R k , R m , R n , R t , R u , R v , R w , R x , R y , and R z are independently hydrogen or substituted or unsubstituted alkyl, wherein the transition metal complex is covalently coupled to the spacer.
