Preparation, Characterization, and Photoelectric Properties of a Covalently Self-Assembled Monolayer of Ferrocenyl Hemicyanine
A monolayer of a ferrocenyl hemicyanine was covalently self-assembled on an indium tin oxide (ITO)-coated glass substrate, and was characterized by UV/Vis absorption and X-ray photoelectron spectroscopy, and cyclic voltammetry. The photoelectrochemical properties and mechanism of photocurrent
generation have also been studied. This monolayer film was found to exhibit a large anodic photocurrent density of 0.13 μA/cm2 with the highest photoelectric yield of 3.32% under irradiation of white light (730 nm > λ > 325 nm) at a bias potential of
+0.4 V versus saturated calomel electrode.
