Polyferrocenylsilanes conductivity

The semiconductive nature of polyferrocenylsilanes makes them excellent candidates for applications where some conductivity is needed but high values are not... 

Water-soluble organic polymers are of considerable commercial importance, whereas few examples of water-soluble metal-containing polymers have been reported. Both cationic and anionic water-soluble polyferrocenylsilanes have been prepared by a variety of different synthetic methodologies [132-138]. These materials are of potential interest as electrode materials and as redox-active polymeric electrolytes, the ionic conductivity of which might be tuned by oxidation of the iron centers. Based on the potential formation of micellar aggregates, these materials may also prove useful as redox-active encapsulation agents [139]. Furthermore, various water-soluble ferrocenium salts have been shown to display anti-cancer activity [140]. 

In addition to forming continuous organometallic multilayer thin films, we explored the LbL deposition of polyferrocenylsilane polyions onto, for instance, hydrophilically/hydrophobically modified substrates with the aim of building two-dimensionally patterned organometallic multilayers. In general, surfaces modified with microscopically patterned conducting, luminescent, or redox-active polymer films have potential use in microelectronic and optoelectronic devices and microsensor arrays. Area-selective deposition of polyferrocenylsilane polyions can be an attractive method to obtain two-dimensionally patterned redox active films, which may be used as electrochemically modulated diffraction gratings. ... 

Recently, the enhanced control of bulk and surface ordering of polypeptides has been employed to drive the processing and self-assembly of conductive rigid segments. Mainly triblock copolymer structures have been studied (see the following section). Manners and Winnik (Wang et al., 2008) synthesized a new type of metaUopolymer-polypeptide block copolymer poly(ferrocenyldimethylsilane)-fc-poly(8-benzyloxycarbonyl-L-lysine) (PFS-( -PZLLys) and studied their self-organization behavior in both the bulk state and in solution. In the bulk state, a cylindrical in-lamellar structure was observed in a compositionally asymmetric sample. Rod-like micelles with a polyferrocenylsilane core formed in a polypeptide selective solvent alone or in the presence of a common solvent.
