Effect of the graft ratio on the properties of polythiophene-g-poly(ethylene glycol)

Graft copolymers formed by anchoring poly(ethylene glycol) (PEG) chains to conjugated polythiophene have been prepared by copolymerizing two compounds: unsubstituted -terthiophene (Th-3) and a thiophene-derived macromonomer having an -terthiophene conjugated sequence and one Th-3 bearing a PEG chain...

The grafting ratio of the resulting copolymers (PTh3*-g-PEG), which were obtained using 75:25 and 50:50 Th-3-PEG(2000):Th-3 weight ratios, is significantly smaller than that of copolymers derived from polymerization of macromonomers consisting of a -pentathiophene sequence in which the central ring bears a PEG chain of M-w = 2000 (PTh5-g-PEG). The electroactivity and electrochemical stability of PTh3*-g-PEG is not only higher than that of PTh5-g-PEG but also higher than that of PTh3, the latter presenting a very compact structure that makes difficult the access and escape of dopant ions into the polymeric matrix during the redox processes. Furthermore, the optical -(*) lowest transition energy of PTh3*-g-PEG is lower than that of both PTh5-g-PEG and PTh3. These properties, combined with suitable wettability and roughness, result in an excellent behavior as bioactive platform of PTh3*-g-PEG copolymers, which are more biocompatible, in terms of cellular adhesion and proliferation, and electro-compatible than PTh5-g-PEG.
