Manipulating the interfacial/surface structure of ligand-stabilized
atomically precise metal nanoclusters (NCs) is one of the central
tasks in nanoscience because surface motifs are directly related to
key properties of nanomaterials. Although great progress has been
made in engineering the surface of gold and silver nanoclusters, parallel
studies on lighter copper analogues hitherto remain unexplored. In
this work, we report the design, synthesis, and structure of a new
class of copper nanoclusters featuring virtually identical kernels
but different surface motifs. The four Cu29 nanoclusters
share the same Cu13 kernel with unprecedented anticuboctahedral
architecture. Finely modulating synthetic parameters endows the Cu13 core with diverse surface structures, thus affording the
Cu29 series with labile surface coatings. More interestingly,
the slight surface modification results in distinct optical and catalytic
properties of the cluster compounds, highlighting the importance of
the surface structure in shaping the behaviors of copper nanomolecules.
This work not only exemplifies the efficiency of surface engineering
for controlling properties of well-defined copper nanoclusters but
also provides a new family of Cu materials with a clear molecular
structure and controlled surface motifs that hold great promise in
studying structure–property relationships.
Domperidone is a powerful peripheral dopamine receptor antagonist; however, a systematic review of the synthetic methods and processes of this drug has not been reported so far.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
