Preliminary experiments are reported on light-induced charge separation by quenching electronically excited species with formation of insoluble precipitates.Irradiation of acceptor-donor mixtures of 3-dimethylaminoperylene metaphosphate/tetramethyl-p-phenylenediamine (TMPD) and of Ag+/perylene, respectively, in methylene chloride and with tetrabutylammonium perchlorate as supporing electrolyte formed precipitates of TMPD+ClO4- and Ag, respectively.The precipitates were separated from the solution by a platinum filter in a flow cell, which served as a simple battery for conversion of stored chemical energy into electrical energy.The quantum yield was about 1E-6 and the battery voltage about 60 mV.
