Ferrocenophane-Based Polymers

In 1992, Brandt and Rauchfuss reported the synthesis of polyferrocenylene persulfides via ROP of and desulfurization of [3]-trithiaferrocenes. High MW linear and network poly(ferrocene persulfide)s were produced by reaction of the trithiaferrocenes with These disulfide-linked ferrocene polymers 

A number of conjugated ferrocene-based polymers have been synthesized via ROMP of ferrocenophanes that possess bridging olefinic units.Buretea and Tilley reported the homopolymerization of ansa-vinyleneferrocene and its copolymerization with norbomene. While the homopolymers were insoluble materials that had a conductivity of 10 0 cm , the copolymer had and values of 21,000 and 

A number of studies have focused on the synthesis of polymers with functionalized sidechains. For example, long-chain alkyl, chloroalkyl, chloro, and alkoxy substitutes polyferrocenylsilanes have been reported. Polymers with

Ring-opening metathesis polymerization (ROMP) of ferrocenophanes containing bridging olefinic groups (45, 46 48) has been examined in order to synthesize conjugated ferrocene-based polymers (93-95). The poljuners synthesized... 

Copolymerization reactions with ferrocenophanes using transition metal catalysts have also been accomplished. The self-assembly of block copolymers has been examined, and polymers with dimethylsiloxane or ethyleneoxide blocks have been found to be soluble in aqueous solution. These ferrocene-based polymers have been found to self-assemble in solution, and their morphologies have been investigated. A number of water-soluble anionic (26) and cationic (27) polyelectrolytes have also been produced by sidechain functionalization.

Homo- and copolymers formed from ROP of [l]ferrocenophanes have been tested for a number of applications. These classes of ferrocene-based polymers have been examined by Vancso et al. as nanolithographic and plasma etch resistant materials. Panned et al. have described ferrocenylsilylene polymer coatings as tapered optical-fiber sensors in the detection of ammonia and carbon dioxide. ...
