英文摘要 | Synthesis of a novel small molecule accepter with perylenediimide linked through thiophene ring with triphenylamine is described. Introducing thiophene unit leads to extending the molecular absorption spectrum to the range of 330 nm-700 nm. The molecule showed the lowest unoccupied molecular orbital level (LUMO) of -3.80 eV and the highest occupied molecular orbital level (HOMO) of -5.60 eV. The X-ray Diffraction (XRD) spectra confirmed that the molecule self-assemble in the solid phase by edge-to-face aromatic interaction, and the addition of 1, 8-diiodooctane in the solvent can adjust its stacking, and thus improve the crystallinity and electron mobility. Solution-processed bulk-hetero-junction organic solar cells constructed using the small molecule as acceptor and the polymer of PBDTTTC-T as donor showed the best efficiency of 1.92%.
