摘要:
In this work, we present a new convenient synthesis leading to a highly regioregular poly(3-octylthiophene) (POT). The stable polymerizable precursor, bearing an iodo and a boronic ester derivative in the 2 and 5 positions, respectively, was obtained in two steps from 3-octylthiophene. Its polymerization, in the presence of palladium(II) acetate, gave a POT containing 96-97% of head-tail to head-tail (HT-HT) couplings. (C) 1998 Elsevier Science S.A. All rights reserved.
