| Abstract | A series of star-shaped macromols. bearing distinct sym. branches with alternating organoiron complexes and azobenzene moieties were synthesized using both convergent and divergent approaches. The various azo dye and organoiron-contg. branches were reacted with multifunctional cores via metal-mediated nucleophilic arom. substitution and ester condensation reactions to afford multi-substituted three- and four-arm star-shaped oligomers. UV-vis spectral studies of complexes 15 and 22 (λ max = 435 and 427 nm, resp.) show bathochromic shifts (λ max = 576 and 558, resp.) at various HCl concns. indicating their use as potential acid sensors. Cyclic voltammetric studies of the octa-iron oligomer 22 were reversibly reduced at E 1/2 = -1.53 V. [on SciFinder(R)] |
