A carbon–oxygen-bridged hexacyclic ladder-type building block for low-bandgap nonfullerene acceptors

Author affiliations

Abstract

A hexacyclic carbon–oxygen-bridged ladder-type unit, COi6, was developed. Three nonfullerene acceptors (COi6IC, COi6FIC and COi6DFIC) based on COi6 were prepared. They present low optical bandgaps of 1.31–1.37 eV and strong absorbance in the near-infrared region. A 9.12% power conversion efficiency was achieved from the solar cells based on COi6FIC and a wide-bandgap copolymer donor (FTAZ).
