Atomically precise nanoclusters with reversible isomeric transformation for rotary nanomotors.

ABSTRACT: Thermal-stimuli responsive nanomaterials hold great promise in designing multifunctional intelligent devices for a wide range of applications. In this work, a reversible isomeric transformation in an atomically precise nanocluster is reported. We show that biicosahedral [Au₁₃Ag₁₂(PPh₃)₁₀Cl₈]SbF₆ nanoclusters composed of two icosahedral Au₇Ag₆ units by sharing one common Au vertex can produce two temperature-responsive conformational isomers with complete reversibility, which forms the basis of a rotary nanomotor driven by temperature. Differential scanning calorimetry analysis on the reversible isomeric transformation demonstrates that the Gibbs free energy is the driving force for the transformation. T
