Abstract: Growing steps of CdS clusters in aqueous solution containingHOCH2CH2SH(2-mercaptoethanol, RSH) was investigated by means of stopped flow optical spectroscopy and proton NMR spectroscopy. When the amount ofRS−was 4 times larger thanCd2+ions at alkaline pH, the growing cluster showed the change in the absorption peak via 242, 260, 280, 308, and 315 nm. Initial three peaks were assigned to[Cd1(SR)4]2−,[S1Cd4(SR)12]6−, and[S1Cd8(SR)16]2−, respectively. Among them, the cluster at 280 nm was very stable, comparable with the reported thiophenolate cluster[S1Cd8(SPh)16]2−. The relationship between the size and the absorption maximum for ultrasmall CdS particles reported was continuous to that obtained for the clusters in the present study.
