Abstract

Organofluorine compounds have wide-ranging applications in materials, biomaterials, smart materials, liquid crystal displays, solar cells, fuel cells, and numerous consumer goods. Fluoropolymers, including poly(tetrafluoroethylene), poly(vinylidene fluoride), poly(vinyl fluoride), and Nafion (a perfluorinated ion-exchange membrane), are integral part of chemical industry. Fluorinated ionomers are extensively used as proton-exchange membranes in fuel cells. Perfluorinated nanomaterials also have medicinal applications. For example, the oxygen-enriched fluorinated hydrocarbon and polymeric nanomaterials are being developed for use in the photodynamic therapy of cancer. Fluorinated π-conjugated polymeric materials have found applications in the design of photovoltaic devices. All-organic solar cells, consisting of fluorinated materials, afford power conversion efficiencies, as high as 13.1%. Furthermore, fluoropolymers have been used as photoresist materials in the 157nm lithography, as they are transparent at this wave length. Fluorinated dendrimer amphiphiles are used as probes for 19F magnetic resonance imaging probes and in drug delivery. This chapter outlines synthesis and wide-ranging applications of organofluorine-based materials.
