摘要：

A large turn-on effect in the form of a notable photoluminescence (PL) enhancement was observed for an oligo(ethylene glycol)-appended CdS cluster molecule with a Cd10S16 core upon mixing with Cu I in water (see graphic). Analysis by the Job method and size-exclusion chromatography suggested that the turn-on response, which was found to be specific for CuI, is associated with the formation of a CuI-containing multicluster network.
