Patent abstract
Synthesis of regioregular thiophene-based polymers (PTs) and their functionalized counterparts via metal assisted cross-coupling polymerizations utilizing mixed halogen substituted aryl halide monomer precursors. The described method provides a means to control structural homogeneity and regioregularity and the electronic/spectroscopic properties of functionalized PTs, and leads to improved performance of organic semiconductor devices such as OPVs and/or OFETs. Asymmetrical monomers can be used.
