Ferrocenyl-Functionalized Poly(propylenimine) Dendrimers

Abstract

New ferrocenyl dendritic macromolecules based on flexible poly(propylenimine) dendrimer cores, built up to the fifth generation, containing 4, 8, 16, 32, and 64 peripheral ferrocenyl moieties, have been prepared and characterized. Solution electrochemical studies showed that all the ferrocenyl redox centers attached to the dendritic surface are electrochemically independent and that, in CH2Cl2 and THF as solvents, the neutral dendrimers undergo oxidative precipitation onto the electrode surfaces.
