Synthesis and Electrochemistry of Octamethylferrocenyl-Functionalized Dendrimers

摘要: New octamethylferrocenyl dendritic macromolecules are reported. The condensation reaction of aldehyde (1) with polyamines DAB-dend-(NH2)x (x = 4, 8, 16, 32) affords up to the fourth generation octamethylferrocenylimine dendrimers DAB-dend-(NCHFc#)x (2−5). Reduction imine groups leads corresponding octamethylferrocenylmethylamine DAB-dend-(NHCH2Fc#)x (6−9) and 32 units per molecule, respectively. Characterization synthesized by 1H 13C{1H} NMR IR spectroscopy, mass spectrometry, elemental analysis supports their assigned structures. redox activity centers in 6−9 has been characterized cyclic voltammetry. Solution electrochemical studies showed that all attached surface electrochemically independent that, CH2Cl2 as solvent, neutral undergo oxidativ...
