Abstract
Transfer of trispolypyridineruthenium(II) chelates of the type [Ru(chel)3]2+, where chel is 2,2’-bipyridine, 2,2’-bipyrimidine or 2,2’-bipyrazine, in their ground states across the water/1,2-dichloroethane interface was classified as the reversible transfer of a divalent cation. Thermodynamic and transport parameters characterizing this transfer were obtained from voltammetric measurements. Photoexcitation of these chelates gives rise to the photoinduced charge transfer across the water/1,2-dichloroethane interface.
