Using experimentally established sequence of extractions, we were able to fractionate regioregular poly(3-hexylthiophene) (R-P3HT) into four fractions differing significantly in their molecular weight (M n) and exhibiting low polydispersity coefficients. 1H NMR analysis of low molecular fractions en...
