Two-Dimensional Nanosheets from Redox-Active Superatoms.

ABSTRACT: We describe a new approach to synthesize two-dimensional (2D) nanosheets from the bottom-up. We functionalize redox-active superatoms with groups that can direct their assembly into multidimensional solids. We synthesized Co₆Se₈[PEt₂(4-C₆H₄COOH)]₆ and found that it forms a crystalline assembly. The solid-state structure is a three-dimensional (3D) network in which the carboxylic acids form intercluster hydrogen bonds. We modify the self-assembly by replacing the reversible hydrogen bonds that hold the superatoms together with zinc carboxylate bonds via the solvothermal reaction of Co₆Se₈[PEt₂(4-C₆H₄COOH)]₆ with Zn(NO₃)₂. We obtain two typ
