Ferrocene-functionalized polymer applications

Ferrocene-Functionalized Polymer Brushes Synthesis and Applications 67... 

A comprehensive summary of the syntheses and applications of the ferrocene polymer brushes has been presented. Ferrocene-functionalized polymer brushes covalently bonded or physisorbed on solid substrate surfaces can be readily prepared via well-known surface modification techniques, such as surface-initiated polymerizations, reaction of the end-functional groups of polymer chains with substrate surfaces, and host-guest interaction. These electroactive polymer brushes have found applications in biosensors, anion-exchange chromatography, and redox-controlled modification of surface wetting properties. 

Ferrocene-containing polymers with long spacers have been prepared as new NLO materials for SHG applications (e.g., frequency doubling).The use of ferrocene derivatives in this area is attractive as a result of their demonstrated large hyperpolarizability values combined with their thermal and photochemical stability. These factors make polyferrocenes desirable candidates for use as processable NLO materials. The polyurethane co-polymer 123 was synthesized using a functional ferrocene monomer (Equation (45)) and was well characterized the molecular weight was estimated by GPC to be = 7,600. The two possible orientations of the ferrocene NLO chromophore monomer unit that correspond to opposite dipole orientations were both present in the main chain.
