Ferrocene-based Linear Polymers

The process is shown to involve the removal of one electron for each ferrocenyl subunits in that the number of electrons consumed in controlled potential electrolysis ( app) is essentially equal to the degree 

The oxidation potential of the polymer is not very different from that of the vinylferrocene monomer, which in turn is not very different from that of ferrocene. 

It is important to note that the appearance of a single oxidation process for PVF indicates that there is no interaction between the ferrocene subunits in the polymer chain, which means that the carbon chain creates a barrier blocking the electronic communication between the ferrocenyl groups. 

As seen, it affords a single oxidation process the cyclic voltammetric profile of which is very close to that expected for the mechanism  

In fact, the parameter zp/v remains constant with the scan rate (see Chapter 2, Section 1.6).

Ferrocene-based Linear Polymers. The first derivative that was studied from the electrochemical point of view was polyvinylferrocene (PVF). As illustrated in Figure 25, it displays a single oxidation process, which in some solvents is affected by problems of adsorption of the oxidation product (though not of the ideal Langmuir isotherm type discussed in Chapter 2, Section 1.6). 

Ferrocene-based Branched Polymers (Dendrimers). One of the topics in macromolecular chemistry is constituted by dendrimers, or hyperbranched macromolecules of tridimensional globular structure, the surface of which is characterized by a large number of functional groups, Scheme 4. Such functionalities impart to the molecules solubility, viscosity and thermal properties different from those of the common linear polymers.38c,d 44... 

BpyP = 3,6-bis(4 -pyridyl-l -pyridinio) pyridazine) consists of 1-D infinite chains (1-D linear chain Scheme 5a), in which photoelectron transfer from Cl to BPyP occurs, generating the pyridyl radical. Solid state cyclic voltammograms of several 1-D coordination polymers containing ferrocene-based bidentate ligands (1-D linear chain Scheme 5a) have been reported. ... 

In this paper we will discuss the i thesis and characterization of ferrocene based NLOPs and a study of their orientation and relaxation behavior using NLO-spectroscopy. ° Included in this work is the ( thesis of a new class of fluorenyl-ferrocene NLO-phores and a detailed study of their chemistry and the linear optical properties of the new NLO-phores. The fluorenyl-ferrocene NLO-phore/monomer was successfully incorporated in the backbone of a conjugated organic polymer.
