Poly 3-thiophenylacetic acid -based polymers

Apart from the examples of PTs with carboxylic acid groups, a wide range of copolymers with poly(thiophene) and poly(3-thiophenylacetic acid) 

Indeed, a significant enhancement of PCE was obtained by Wadgaonkar et al. [CHH 12] with a copolymer, PPV6, with alternating poly[2-[2 ,5 -bis(2 -ethylhexyloxy)phenyl]-l,4-phenylenevinylene] unit with MEH-PPV. The performance of the polymer showed a 10-fold increase in the device performance with PCE equal to 3% compared to the base polymer without
