摘要
The polyelectrolytes-organometallic system is prepared and applied to the photocurrent generation. The viologen-containing polymers (polyproylviologen) have two Br- counter ions and are easily soluble in water. The viologen-containing polyelectrolyte multilayers were formed by layer-by-layer deposition method. And as a photosensitizer, RuL2 (CNS)(2) are easily incorporated in the multilayer films by a ion-exchange method. The energy levels of LUMO of RuL2(CNS)(2), viologen, and ITO are well arranged and form an acceptor-sensitizer system. The photocurrent measurement of the systems shows excellent photocurrent generation: 1200 nA/cm(2) under AM 1.5 condition for 4.5 bilayers sample. (c) 2006 Elsevier B.V. All rights reserved.
