Tailor-made supramolecular building units prepared by anionic polymerization techniques

3-7 Different kinds of block copolymers with varying chain length and different transition metal ions can be designed (e.g. A-B, A-B-A, A-B-C, etc.) which are of great importance for fundamental physical-chemical investigations as well as for practical applications due to their unique properties. In this contribution we report on our first experiments to achieve well
