1. An oligomeric complex having the structure: wherein: each M is independently a metal atom; eachis independently a multidentate ligand;
each linker is independently an optionally substituted C2-30 aliphatic group wherein one or more carbons are optionally and independently replaced by —Cy-, —NRy—, —N(Ry)C(O)—, —C(O)N(Ry)—, —N(Ry)C(O)O—, —OC(O)N(Ry)—, —N(Ry)C(O) N(Ry)—, —OC(O)O—, —O—, —C(O)—, —OC(O)—, —C(O)O—, —S—, —Si(Ry)2—, —SO—, —SO2—, —C(═S)—, —C(═NRy)—, or —N═N—, wherein:
each —Cy- is independently an optionally substituted 3-8 membered bivalent, saturated, partially unsaturated, or aryl ring having 0-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an optionally substituted 8-12 membered bivalent saturated, partially unsaturated, or aryl bicyclic ring having 0-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur; andeach Ry is independently —H, or an optionally substituted radical selected from the group consisting of C1-6 aliphatic, phenyl, a 3-7 membered saturated or partially unsaturated carbocyclic ring, a 3-7 membered saturated or partially unsaturated monocyclic heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 5-6 membered heteroaryl ring having 1-3 heteroatoms independently selected from nitrogen, oxygen, or sulfur, and 8- to 10-membered aryl; and n is from 1 to 50; wherein the oligomeric complex is substituted with one or more activating groups ;
where is a linking moiety covalently coupled to the ligand system, m is an integer from 1 to 4 representing the number of Z groups present on an individual linker moiety;
and each Z is independently an activating functional group; and wherein the repeating units of n are optionally joined to form a cyclic oligomeric complex.
