Superfluorinated and NIR-luminescent gold nanoclusters.

A novel class of superfluorinated and NIR-luminescent gold nanoclusters were obtained starting from a branched thiol, bearing 27 equivalent 19F atoms per molecule. These unprecedented clusters combine in a unique nanosystem both NIR photoluminescence and 19F NMR properties, thus representing a promising multimodal platform for bioimaging applications.
