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