A compound having at least one perfluorovinyl group and at least one functional group is suitable for reacting with and/or forming polymers. The compound is preferably of Formula I: (G)n-R-(X--CF.dbd.CF.sub.2).sub.m wherein R represents an optionally substituted hydrocarbyl group, X represents any group which links R and a perfluorovinyl group; n is the number of G groups, m is the number of (XCF.dbd.CF.sub.2) groups; and G represents any reactive functional group or a group convertible into a reactive functional groups. A process for preparing a compound of Formula I comprises the steps of: (a) preparing a 2-halotetrafluoro compound of the Formula III: (Q--CF.sub.2 --CF.sub.2 -X).sub.m -R-(G").sub.n wherein R, X, m and n are as described for Formula I and Q is bromine, chlorine or iodine; and G" is a functional group, or a functional group suitable for conversion into G; (b) chemically modifying group G" to produce functional group G; and (c) dehalogenating the 2-halotetrafluoro compound to form the corresponding trifluorovinyl compound.

Compositions and articles including host polymers and chromophores and methods of producing the same are provided. In an exemplary embodiment, an article includes a host polymer with a host polymer refractive index. The article also includes a chromophore with a chromophore refractive index that is greater than the host polymer refractive index. The chromophore refractive index changes with changes in an electric field, and the chromophore is dissolved within the host polymer. The article has an article refractive index that is between the host polymer refractive index and the chromophore refractive index.
Rylene dyes functionalized with varying numbers of phenyl trifluorovinyl ether (TFVE) moieties were subjected to a thermal emulsion polymerization to yield shape-persistent, water-soluble chromophore nanoparticles. Perylene and terrylene diimide derivatives containing either two or four phenyl TFVE functional groups were synthesized and subjected to thermal emulsion polymerization in tetraglyme. Dynamic light scattering measurements indicated that particles with sizes ranging from 70 to 100 nm were obtained in tetraglyme, depending on monomer concentration. The photophysical properties of individual monomers were preserved in the nanoemulsions, and emission colors could be tuned between yellow, orange, red, and deep red. The nanoparticles were found to retain their shape upon dissolution into water, and the resulting water suspensions displayed moderate to high fluorescence quantum yield:
