Abstract

Novel long oligothiophenes incorporated with four fullerenes (2C ₆₀-16T-2C₆₀ and 2C₆₀-24T-2C₆₀) have been synthesized with the aim of developing good single-component photovoltaic materials. The tetracosithiophene derivative 2C₆₀-24T-2C ₆₀, despite its giant structure, is rather more tractable regarding solubility than the hexadecithiophene derivative 2C₆₀-16T-2C ₆₀. The electronic absorption and emission spectra of 2C ₆₀-24T-2C₆₀ indicated no electronic interaction in the ground state but efficient intramolecular electron transfer in the excited state. The sandwich device of the Al/2C₆₀-24T-2C₆₀/Au structure showed a marked photocurrent upon illumination with monochromatic light from the Al side. The incident-photon to converted-electron ratio (IPCE) is 14%.
