Anson-Bard equation

Cyclic voltammetry of all the ferrocenyl dendrimers on a Pt anode showed all the ferrocenyl centers to be equivalent as only one wave was observed. It was possible to avoid adsorption even using CH2CI2 for the small ferrocenyl dendrimers, but the use of MeCN was necessary for the medium-sized ones (27-Fc, 54-Fc, and 81-Fc). Finally, adsorption could not be avoided even with MeCN for the 243-Fc dendrimer. From the intensity of the wave, the number of ferrocenyl units could be estimated using the Anson-Bard equation [75], and the numbers found were within 5 % of the branch numbers except in the case of the 243-Fc dendrimer, for which the experimental number was too high (250) because of the adsorp-...
