Traditionally, allosteric effects describe how the binding of a ligand at one site of a protein alters the properties of a distant site on the same protein. In this work, we introduce allosteric effects as a strategy for site-differentiation of atomically precise M/Co/Se nanoclusters with multiple edge sites. When M = Fe or Cr, we demonstrate how the allosteric effects guide the differential stoichiometric and catalytic reactivity of the edge sites. When M = Zn, we demonstrate that the allostericity is redox-switchable, and can be harnessed as a guiding force in the assembly of one- and two-dimensional atomically precise nanomaterials.
