An interesting example of a system whose components become mechanically bound upon surface immobilization is rotaxane trans-21 (Fig. 13.24), consisting of a ferrocene-functionalized /3-cyclodextrin (fi-CD) macrocycle threaded on a molecule containing a photoisomerizable azobenzene unity and a long alkyl chain.33 A monolayer of trans-21 was self-assembled on a gold electrode. Therefore, the ring... 

The LBL self-assembly onto the CD functionalized surface requires at least two complementary substrates in order that multiple layers can be built up upon repeated alternating applications of the substrates, until a desired thickness has been achieved. Reinhoudt and coworkers chose the self-assembled interaction between CD-modified gold nanoparticles and either adamantyl- or ferrocene-functionalized dendrimers, which in turn were composed either of poly(propyleni-mine) (PPI) or poly(amidoamine) (PAMAM) [118, 122]. 

As illustrated in Figure 5.23, Willner et al. [49] have developed a light-driven molecular shuttle. This device consists of a ferrocene-functionalized /3-cyclodextrin...

Reaction of the zinc-organyl with -chlotoiodobenzene in the presence of 5mol% PdCl2(DPPF) gives a bicyclic benzyl-substituted tetrahydrofuran in 61% yield (DPPF = l,l -bis(diphenylphosphino)ferrocene). Functional groups such as esters are tolerated in these reactions < 1996TL5865>. 

The electrochemical properties of ferrocene-functionalized dendrimers have been studied also in the presence of )8-cyclodextrin f -CD), which is a well-known inclu-... 

A phthalocyanine core was functionalized with four, eight, and 16 ferrocenyl units (compounds 49-51) [67]. Cyclic voltammetry experiments in DMF or CH2CI2 showed the presence of many quasi-reversible waves. All the ferrocenyl units behave independently, giving rise in all three compounds to a single oxidation wave, which is accompanied by one or two oxidation and by two or three reduction processes due to the phthalocyanine rt-system. For 51, the presence of a stripping peak indicates precipitation of the oxidized product in CH2CI2, as often observed in ferrocene-functionalized dendrimers (see Section 9.4.1). 

A wide range of conventional organic type polymers has been used for modification with the ferrocene functional group. Treatment of polystyrene with lithioferrocene or dilithioferrocene led to incorporation of the ferrocene as a pendant group [59]. Another interesting example is the preparation of a ferrocene-containing ionomer... 

In the synthesis of ferrocene-functionalized polypyrrole systems, numerous derivatives are readily obtained by substitution at either the 3-position of the ring or on the nitrogen of the pyrrole prior to polymerization. It was reported that polymers with both metallic properties and enhanced solubility may be synthesized by judicious derivatization and choice of polymerization conditions, such as a variety of processing solvents [67, 68].
