from adapting a coplanar structure with a short π-stacking distance in the solid state. We furthermore show that incorporation of less space filling units in the form of unsubstituted thiophene units into the polymer chain reduces these unfavorable interactions and therefore allows for a more coplanar polymer backbone orientation and a shorter π-stacking distance in the solid state. These findings are
