Abstract

Survival of the fittest: A profound connection has been found between the structures of thiolated gold clusters and the combinatorial problem of pairing up dots on a surface. The bridge is the concept of staple fitness: the fittest combination corresponds to the experimental structure. This connection has been demonstrated for both Au25(SR)18 and Au38(SR)24 (-SR being a thiolate group) and applied to predict a promising structure for the recently synthesized Au19(SR)13.
