New 4,5-diaza-9,9'-spirobifluorene derivative 8 with two electron-accepting perylene diimide moieties has been prepared. The compound 8 was characterized by NMR spectroscopy, elemental analysis, UV-spectroscopy and cyclic voltammetry. Energies of HOMO/LUMO levels are of -5.81 eV/-3.89 eV; Egopt and Egech values are of 1.75 eV and 1.92 eV, respectively. Low-lying energy levels and strong absorption in the visible region of UV- spectrum indicate the potential use of the compound 8 as a new promising electron acceptor in nonfullerene polymer solar cells.
