The Relationship

Growing steps of CdS clusters in aqueous solution containing HOCH 2CH2 SH (2-mercaptoethanol, RSH) was investigated by means of stopped flow optical spectroscopy and proton NMR spectroscopy. When the amount of RS − was 4 times larger than Cd 2+ 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 [ Cd 1( SR )4]2−, [ S 1 Cd 4(SR)12]6−, and [ S 1 Cd 8( SR )16]2−, respectively. Among them, the cluster at 280 nm was very stable, comparable with the reported thiophenolate cluster [ S 1 Cd 8( 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.
