Outline of Final Research Achievements

In this work, the polymers for organic photovoltaics were synthesized based on the donor-acceptor fused molecules. The polymer that consists of a donor-acceptor fused molecule and an electron-donating bithiophene showed CT absorption band from HOMO that delocalized over polymer backbone to LUMO localized on thiadiazole moiety, resulting in expansion of the absorption band in long wavelength region. On the other hand, combination of donor-acceptor fused molecules and an electron accepting diketopyrrolopyrrole exhibited absorption edge over 900 nm and the LUMO energy of around -3.9 eV, which value is nearly lowest energy for electron transfer to take place, and the HOMO energy of around -5.3 eV.
The results provide the ways to expand the absorption band of the polymer and synthesize narrow band gap polymer with low LUMO energy.
