Strain and hueckel aromaticity: Driving forces for a promising new generation of electron acceptors in organic electronics

(Figure Presented) Straining at the leash: The main features of electron-accepting materials with a 9,9′-bifluorenylidene backbone are strain relief and a gain in aromaticity. These dimers (see picture) exhibit absorption near the red spectral region (ca. 600 nm) and HOMO (5.58-5.06 eV) and LUMO (3.37-3.09 eV) energy levels, which, together with high solubility and thermal stability render these materials attractive acceptors for bulk heterojunction (BHJ) solar cells.
