  • Synthesis, characterization of bay-substituted perylene diimide based D-A-D type small molecules and their applications as a non-fullerene electron acceptor in polymer solar cells

    • Authors: Ganesamoorthy, Ramasamy; Vijayaraghavan, Rajagopalan; Ramki, K.; Sakthivel, Pachagounder (2018)

  • We report a series of bay substituted perylene diimide based donor-acceptor-donor (D-A-D) type small molecule acceptor derivatives such as S-I, S-II, S-III and S-IV for small molecule based organic solar cell (SM-OSC) applications. The electron rich thiophene derivatives such as thiophene, 2-hexylthiophene, 2,2'-bithiophene, and 5-hexyl-2,2'-bithiophenewere used as a donor (D), and perylene diimidewas used as an acceptor (A). The synthesized small molecules were confirmed by FT-IR, NMR, and HR-MS. The small molecules showed wide and strong absorption in the UV-vis region up to 750 nm, which reduced the optical band gap to<2 eV. The calculated highest occupied molecular orbital (HOMO) ...
