About project A9:
Conjugated polymer nanoparticles are promising building blocks for functional materials, but concepts to introduce and control shape anisotropy are lacking to date. Here, we investigate how the shape of such particles can be affected by crystalline order and by the rigid chain conformation specific to many conjugated polymers. In heterophase polymerizations and in post-polymerization procedures, controlled chain growth processes are sought to this end. As a means to obtain the essential knowledge of intra-particle molecular chain conformations that determine particle shape, electron paramagnetic resonance is developed.
