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.

New electron-deficient and soluble indenofluorene-based and bisindenofluorene-based ladder-type building blocks embedding carbonyl and dicyanovinylene functionalities were synthesized, and their optical and electrochemical properties were characterized. These derivatives exhibit optical band gaps of 1.83 to 2.44 eV and low LUMO energies of -3.24 to -4.30 eV, representing a promising new building block class for n-type polymeric electronic materials.
