- 論文の詳細を見る
A tri-branched tri-anchoring organic dye (Dye 2) consisting of one donor (D) in the center, three $\pi$ bridges, and three acceptor (A) groups in the order of D–$\pi$–A was designed and each A group ended with a COOH anchoring group. The Dye 2-sensitized TiO2 exhibited a significantly improved photoelectrochemical response under visible light illumination, compared to TiO2 sensitized with a mono-anchoring dye (Dye 1). It is due to the enhanced optical density and more efficient interfacial electron transfer from the photoexcited dye to the TiO2.
