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.

High-yield Pd-catalyzed syntheses of constitutionally homogeneous, n-alkyl-substituted oligo-p-phenyls having three to fifteen benzene rings connected to each other exclusively in the 1,4-(para-) fashion are reported. Most of the oligomers described readily dissolve in common organic solvents. Furthermore, their thermal phase-transition temperatures show that some of these rodlike oligomers can exist in different crystalline modifications and/or form liquid-crystalline mesophases.

Effects of alkyl or alkyloxy side chains in poly[4,6-bis(3′-dodecylthien-2′-yl)thieno-[3,4- c ][1,2,5]thiadiazole-5′,5′-diyl- alt -2,5-di(alkyl or alkyloxy)-1,4-phenylene]: Synthesis, photophysics, and spectroelectrochemical and photovoltaic properties
alkyloxy side chain exhibits a lower ionization potential than that of CDTDP due to the stronger donor character of the substituted benzene unit, which narrows the bandgap value to 1.15 eV compared to that of 1.3 eV for CDTDP. Both copolymers exhibited interesting electrochromism. Spectroelectrochemical properties are shown for both oxidation and reduction. Optical switching is demonstrated and it is shown
