Summary
This thesis is concerned with original work on the tailor‐made synthesis, characterization and
application of well‐defined semiconductor donor‐acceptor (D‐A) block copolymers for high‐
performance organic field effect transistors and organic photovoltaics. Two types of D‐A
block copolymer architectures are presented: Amorphous‐crystalline block copolymers and
crystalline‐crystalline block copolymers. The materials developed are complex in terms of
their synthesis, since organic methods have to be combined with one or more
polymerization methods. The importance of D‐A block copolymers is illustrated by their
capability to microphase separate into domain sizes commensurate to the exciton diffusion
length, which makes such materials highly suitable for efficient charge separation and charge
transport. The self‐assembling behav
