New conjugated polymers that incorporate dihexylanthradithiophene (DHADT) in the main chain were prepared by Stille and Sonogashira cross-coupling polymerization reactions. The polymerization chemistry is enabled by a soluble 5,11-dibromodihexylanthradithiophene monomer that is capable of cross-coupling reactions. Four readily soluble DHADT containing co-polymers were prepared and characterized experimentally and computationally. These polymers possess HOMO energies of -5.18 eV to -5.43 eV and
