Abstract

original image

Semi-random P3HT analogs and P3HT were synthesized by direct arylation polymerization (DARP) and Stille polycondensation. In several cases, both methods provide polymers with similar molecular weights and polydispersities. Although these two synthetic protocols are strategically similar, preliminary evidence suggests that they give different linkage patterns in the polymers. This translates into different polymer properties as studied by UV–vis, GIXRD, 1H NMR, 13C NMR, DSC, and TGA.
