Down to the bare bones : Small‐molecule zwitterionic materials were found to be more efficient as charge‐injection materials in an organic electronic device than a previously described polymer (see structures). Furthermore, the superior device performance observed for 1 indicates that it is not necessary to focus only on π‐delocalized systems and that solid ionic liquids may be promising alternative candidates for charge‐injection materials.
