Abstract
The two homochiral AgIRhIII nanoclusters, Δ6/Λ6-[Ag11S{Rh(apt)3}6]9+ ([1]9+) and Δ6/Λ6-[Ag13S{Rh(apt)3}6]11+ ([2]11+), in which Ag11S and Ag13S cluster cores, respectively, are protected by fac-[Rh(apt)3] metalloligands, were newly synthesized from fac-[Rh(apt)3] (Hapt = 3-aminopropanethiol) and Ag+ in water in combination with sulfide sources. While [1]9+ was produced by using d-penicillamine as a sulfide source, the use of HS- as a sulfide source afforded [2]11+ without causing any precipitation of Ag2S. Cluster [1]9+ was convertible to [2]11+ via the reaction with Ag+, which led to a turn-on-type switch in photoluminescence from nonemissive [1]9+ to emissive [2]11+.
