Chemical design enables the control of conformational polymorphism in functional 2,3-thieno(bis)imide-ended materials.

We report a successful chemical design strategy based on the even-odd alkyl end tailoring, which allows us to promote and control conformational polymorphism in single crystal and thin deposits of thienoimide-based molecular semiconductors (Cx-NT4N).
