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 Cd 10 S 16 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 Cu I , is associated with the formation of a Cu I ‐containing multicluster network.
