Abstract
We have investigated photoinduced conductors and photoelectric conversion materials using new tetrathiafulvalene (TTF) derivatives containing a fluorescent part. In this study, we focused on new TTF molecules 1-3 in which a fluorene molecule was used as a fluorescent part and was connected to the TTF moiety through alkyl or alkene spacers. We discuss the synthesis, electrochemical properties, and optical properties of molecules 1-3. We also investigated the photoelectric conversion functionality by photoelectrochemical method using the thin films of molecules 1-3 that were spin-coated on ITO-coated glass substrate. We observed electric current generations that depend on the absorption spectra of thin films, suggesting that absorbed photons are converted to electric currents on the thin film/ITO electrode.
