摘要：

The synthesis of polylactide-b-polythiophene-b-polylactide block copolymers (PLA-PT-PLA) by the controlled polymerization of D,L-lactide from hydroxyl-terminated telechelic polythiophenes (HO-PT-OH) was reported. The end groups of regioregular, regiorandom, and copolymerized P3ATs were converted into nonfunctionalized end groups (PT) through the use of the halogen-magnesium exchange reaction followed by hydrolysis. PT polymers were converted to the bis-aldehyde polymers (HCO-PT-COH) using a Vilsmeier transformation and were subsequently reduced with LiAlH4 to the hydroxyl-terminated polythiophenes. The resonance associated with the methylene end group protons at δ ≊ 4.8 ppm in HO-PT-OH was not observed upon PLA addition presumably because this resonance had approximately the same chemical shift as one of the main chain PLA protons.
