| Abstract |
Recently, the coordination-driven assembly of well-defined and rigid tetranuclear cobalt clusters, composed of four cobalts and three 2,6-pyridinedicarboxylate (PDA) ligands, through three "strand' isophthalate (PTA) ligands to form a novel metallosupramolecular structure with fascinating triple-stranded helical geometries (TSH) has been first reported by our group. More importantly, TSHs can be considered efficient conceptual supramolecular modules for building higher-order molecular assemblies through the coordination with Co2+ cations induced by the availability of unsaturated oxygens residing on cobalt clusters. Herein, we report the rational design of a variety of functional TSHs through the use of different PTA substitutes, Co8(PDA)6(X-PTA)3(DMF)m(H2O)6-m (X, the functional groups at the 3-position on the benzene ring of substituted PTA ligand = ─C(CH3)3, ─H, ─OCH3, ─NH2, ─OH, ─COOH, and ─Br). The TSHs’ capability of assembling with Co2+ in given reaction conditions to form higher-order structures will be also investigated. In addition, we expect that the rational design of functional groups at given specific sites at molecular level can provide access to unique chemical and physical properties of the resultant metallosupramolecules. |
