Abstract
The invention provides novel gold nanoclusters of the formula Au20(SR)15(weak ligand), wherein each R is independently an organic group, and the weak ligand is a weakly associating gold ligand of Formula I as described herein. The nanocluster can have an approximate molecular weight of 6 kDa. Corresponding dimers of the nanocluster can have an approximate molecular weight of 10 kDa (by SEC). The invention also provides methods of making and using the gold nanoclusters.
