Abstract
The head-tail (HT) sequence length distributions (SLDs) of poly(3-alkylthio phenes) (P3ATs) and related polymers may be obtained from the H NMR spectra . The results show that the regioregular polymers, i.e., those with the hig hest HT content, have broader SLDs than the less regular polymers. The SLD may be used to simulate the characteristic profiles of the pi-pi* absorptio n peaks of P3ATs and related polymers.
