The synthesis of fully conjugated semiconducting para-phenylene ladder polymers by microwave-assisted palladium-mediated double Suzuki and Stille-type reactions has been demonstrated by Scherf and coworkers (Scheme 6.27) [58], The procedure, which yields polymeric material in ca. 10 min, has no adverse effects on the quality of the polymers and displays a high degree of reproducibility. Compared...

It is worth mentioning that purely conjugated semiconducting polymer-based blocks having high rigidity (due to stiff aromatic backbone), are regarded as rod-like or stiff whereas the flexible blocks based on purely...
