Other Organic Polymers with Metallocene-containing Side Groups

DSC measurements on the block copolymers revealed two TgS with values close to those of the individual homopolymers. This thermal behavior is consistent with a

Polypyrrole and polythiophene derivatives with pendant ferrocene groups (e.g. 2.12) have also been prepared using electropolymerization techniques [35]. Studies of these materials by means of in situ conductivity measurements revealed that the redox conduction, due to hole hopping between the ferrocene units, was en- 

This type of approach has been extended to main-chain liquid-crystalline polymers 2.15 with low loadings of ferrocene groups in the side-group structure. In some cases, changes in liquid-crystalline morphology from nematic to smectic have been observed upon oxidation, as the formation of ionic domains facilitates the generation of layered structures (Fig. 2.3) [37]. 

In general, much less work has been reported on side-chain polymers containing metallocenes other than ferrocene. For example, ruthenium and osmium analogues of poly(vinylferrocene) have been described, but their characterization has been fairly limited [16,42,43]. Poly(vinylruthenocene) is reported to be a light-yellow solid with a Tg 250°C, and the preparation of samples with molecular weights of up to

A variety of other organic polymers with metallocene-containing side-groups have been synthesized. However, very few of the materials have been as well studied as PVEc. Crystalline organometallic complexes containing ferrocene...
