|Abstract||Various four-arm organoiron macromols. contg. different azo dye moieties have been prepd. via metal-mediated nucleophilic arom. substitutions and ester condensation reactions. The synthesis of a four-arm organoiron star contg. aryl- and hetaryl-azo chromophores (7) and a cross-linked azo dye-contg. organoiron macromol. (10) are reported as two example models. NMR spectroscopy was used to characterize the reported complexes, with the exception of the cross-linked star (10). UV-vis anal. of azo dyes 4, 5, and 6 were reported as examples.|
