Block Copolymers Containing Polythiophene Segments

1 Combination of GRIM and Living/Controlled Radical Polymerization 

Although many examples have been developed based on GRIM polymerization in conjunction with the living/controlled radical polymerization system, tedious site-transformation reactions as well as the limited control nature of radical polymerization frequently cause broad molecular-weight distributions ( 1.3). Furthermore, a thorough purification process to remove the residual copper catalyst from the products is sometimes essential for optoelectronic application. 

2 Combination of GRIM Polymerization and Living Anionic Polymerization 

The thin films of BCPs can self-assemble into many types of highly ordered nanostructures on a wide variety of substrates after being cast from a number of solvents. Selective etching of one of
