A heptacyclic carbon-oxygen-bridged ladder-type unit, CO i 7, was designed. Two corresponding nonfullerene acceptors, CO i 7IC and CO i 7DFIC, were developed. The single crystal structure of CO i 7IC indicates an S-shaped backbone and a packing via π-π interaction of the end groups. PTB7-Th:CO i 7DF...
