Abstract

The photoinduced electron transfer reactions from nanosized CdS particles synthesized in micelles of cadmium lauryl sulphate and sodium lauryl sulphate to various dialkyl viologens is measured for a molar ratio of cadmium to sulphide ions equal to 2. — The yield of the reduced viologens obtained by CdS irradiations is miximum in the case of C 1 viologen, which decreases gradually with increase in the chaine length of the viologens. Moever, a back electron transfer reaction is observed in the case of C 1, C 3, and C 8 viologens. The addition of sodium lauryl sulphate (NaLS) inhibits the back electron transfer reaction. This is due to strong interactions between methyl viologen and lauryl sulphate, which gives the viologens a hydrophobic character and favors their entrance into the micellar core. This is confirmed by studying the photoelectron transfer from CdS particles to methylviologen laurylsulphate.
