Abstract

The viologen 1,1'-bis[2-(4-methoxyphenyl)-2-oxoethyl]-4,4'-bipyridine-1,1'-diium bromide containing carbonyl units, is studied as an acceptor in photo-sensitized donor-acceptor molecular systems formed in liquid solutions. The photo-electrical properties of the molecular systems are examined by impedance measurements. The results obtained show a photoelectrical response of the viologen-containing donor-acceptor complexes that may be of interest for solar energy utilizing..
