One-pot synthesis of β-cyclodextrin modified Au nanoclusters with near-infrared emission.

β-Cyclodextrin modified gold nanoclusters (AuNCs@β-CD) with near-infrared (NIR) emission were facilely and successfully prepared based on a one-pot and green synthesis route, which provides an interesting and efficient strategy to realize NIR emissive nanoclusters via supramolecular macrocycle modification.
