A new organic photovoltaic polymer (TTF-DA-polymer), a tetrathiafulvalene (TTF, electron donor)-based main-chain polymer and contained fullerene (C60, electron acceptor), was successfully synthesized. Organic charge transfer materials can be applied in the field of molecular switches, sensors, self-assembled redox-active supramolecules and organic field-effect transistors (OFETs). TTF can work as an electron donor (D) and C60 can act as an electron acceptor (A). Therefore, the chemical component of TTF-DA-polymer is a DA dyads system. The chemical structure of TTF-DA-polymer was determined by FT-IR spectroscope, 1H and 13C NMR spectroscopes. Moreover, the electrochemical properties and photoelectric properties were researched by CV, PL, and UV-visible spectrometer. Molecular weight of the TTF-DA-polymer was confirmed by GPC, which was high enough to form the durable film. This work was mainly supported by Basic Science Research Program and BK21Plus Program, Korea. |
