説明
Abstract Ultrathin molecular films consisting of electron donor (D)–acceptor (A) pairs via titanium oxide coordinative bonding have been fabricated on an indium–tinoxide electrode, by using the techniques of self-assembly and surface sol–gel process. Porphyrin and tris (2,2′-bipyridine) ruthenium (II) were used as D, while viologen as A, respectively. The degree of assembling of D and A were characterized by electrochemical and absorption measurements. In the case of the porphyrin–viologen pair, photocurrent generation based on photoinduced electron-transfer was realized, and multilayer formation of porphyrin increased the photocurrents. On the other hand, the ruthenium (II) complex–viologen pair showed very poor photocurrent responses, probably due to much poorer light absorptivity as compared with porphyrin.
