High efficiency photocurrent generation by two-dimensional mixed J-aggregates of cyanine dyes

Mitsuo Kawasaki, Satoshi Aoyama
Chemical Communications: Chem Comm 2004 April 21, (8): 988-9
Two-dimensional mixed J-aggregates of structurally and spectrally analogous anionic cyanine dyes, coadsorbed on a self-assembled monolayer of aminoalkanethiolate on Au(111), generated a high-efficiency (20-30% quantum efficiency) cathodic photocurrent and a significant photovoltaic effect in reversible Fe2+/Fe3+ redox solution.
