Monolayer anchored ferrocenes

For instance, we have recently shown that the monolayer-anchored ferrocene groups are not complexed by hosts such as the anionic calixarene 9 and p-CD[31]. Presumably, these two receptors are strongly solvated in aqueous media so that their approach to the hydrophobic monolayer is unfavorable, thus preventing any significant binding. In contrast, an... 

Beer and co-workers have investigated this concept using self-assembled monolayers of the l,l -bis(alkyl-iV-amido)ferrocene 106 on gold electrodes [72]. The pendant disulphide groups serve to covalently anchor the receptor to the gold surface. In electrochemical experiments on 106 in acetonitrile/dichloro-methane solution, anion-induced cathodic shifts of the ferrocene/ferrocenium...
