Abstract
Disclosed are new conjugated compounds (e.g., monomers and polymers) that include ladder-type moieties which can be used for preparing semiconducting materials. Such conjugated compounds can exhibit high n-type carrier mobility and/or good current modulation characteristics. Compounds of the present teachings also can exhibit ambipolar semiconducting activity. In addition, the compounds of the present teachings can possess certain processing advantages such as solution-processability and/or good stability in ambient conditions.
