Kurzbeschreibung (Abstract)
Most metallopolymers based on kinetically labile transitionmetal complexes are polyelectrolytes and dissolve in polar, coordinating solvents only. In these solutions, solvent molecules can displace the metallopolymers' original ligands and thus cause decomposition. Consequently, such systems are very difficult to characterize. Our adopted strategy to overcome this problem consists of the attachment of apolar substituents which solubilize the metal-containing polymers in non-coordinating solvents. Then, even intrinsically labile chains should behave like inert systems. Based on this strategy, we developed an efficient synthetic access to dendronized metallopolymers. The dendrons were attached very closely to the tetrahedral copper(I) complexes. Positioned in this way, they also increase the materials' solubility in non-coordinating solvents. Moreover, due to their bulkiness, the dendrons should reduce the tendency of the metal-containing polymers to aggregate in solution, and protect the kinetically labile complexes against the attack of competing ligand molecules.
