(a) Molecular structure of random poly(3-hexylthiophene) (ra-P3HT) with HT-HT:HT-HH:TT-HT:HH-TT=1:1:1:1; (b) 1H-NMR spectra of random P3HT with characteristic peaks of protons in thiophene rings in chemical shifts near δ = 7.0 ppm, and characteristic peaks of protons in α-methylene protons of hexyl group in chemical shifts near δ = 2.4–2.8 ppm; (c) Molecular structure of regular P3HT (rg-P3HT) with HT-HT-only structure; (d) 1H-NMR spectra of regular P3HT with characteristic peaks of protons in thiophene rings in chemical shifts near δ = 7.0 ppm, and characteristic peaks of protons in α-methylene protons of hexyl group in chemical shifts near δ = 2.4–2.8 ppm.
