Abstract

We report the synthesis, characterization, and electrochemical properties of bis-PCBM dyad containing 4-nitro-α-cyanostilbene units for potential usage in efficient organic solar cells. The bis-PCBM dyad is fully characterized by NMR, UV–vis absorption, and electrochemical cyclic voltammetry. It is found that the presence of 4-nitro-α-cyanostilbenes affects the cyclic voltammetry and absorption spectrum very little. Whereas the 56 π-electron system in the ...
