Heteroatom substitutions in the end‐groups of three diketopyrrolopyrrole‐containing small molecules are investigated to evaluate how such substitutions affect physical properties, charge transport, and the performance in bulk heterojunction solar cells. As reported by Thuc‐Quyen Nguyen and co‐workers on page 47 , the single‐crystal structures of three compounds reveal the differences in material properties arise from changes in intra‐ and intermolecular interactions in the solid state, which are caused by heteroatom substitutions. This study demonstrates a systematic investigation of structure‐property relationships in conjugated small molecules.
