Abstract

A self-assembled monolayer (SAM) of a C₆₀-triosmium cluster complex Os₃(CO)₇(CNR)(CNR-)(μ₃-η²:η²:η²-C₆₀) (ZnP-C₆₀; R = (CH₂)₃Si(OEt)₃, R- = ZnP) on an ITO surface exhibits ideal electrochemical responses as well as remarkable enhancement of the photocurrent generation. The diazabicyclooctane (DABCO) binding (ZnP)-C₆₀/ITO/AsA/Pt cell shows the highest photocurrent generation quantum yield (19.5%) ever reported for the molecular photovoltaic cells based on the covalently linked donor-acceptor dyad structures. The high efficiency in photocurrent generation is ascribed to an efficient electron transfer from photoexcited porphyrin to fullerene, revealed by fluorescence lifetime measurements and transient absorption decay profiles. These results provide valuable information on the new strategy for the construction of molecular photonic devices and artificial photosynthetic systems on ITO electrodes.
