Synthesis of Anthradithiophene Containing Conjugated Polymers via a Cross-coupling Strategy

submitted on 23.07.2020 and posted on 24.07.2020 by Waseem A. Hussain, Kyle Plunkett
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 LUMO energies of -3.0 eV to -2.82 eV. The notable optical features include broad absorption and band gaps ranging from 1.62 eV to 2.15 eV.
