Abstract

Atomically-precise gold nanoclusters covered with thiol ligands are attractive candidates for biophotonics applications. We show that their covalent linking may offer a pathway toward atomically-precise materials with enhanced nonlinear optical properties. Clusters oligomerization leads to moderate modification of the linear optical properties, but has significant impact on their two-photon absorption performance.
