In addition, TEM EDX of a nanocomposite containing worm-like structures (5d) proved that the iron containing SCO CP is only located inside the polymeric structure and no iron can be detected outside of the micelles. Thus, with the presented approach both, size and morphology, of coordination polymers and networks can be tailored in a welldefined way. This concept can be transferred to a wide range of coordination compounds with different functionalities. Furthermore, the obtained structures are stable both in the solid state and in solution, opening ways different types of processing for application, for example as sensor material.
