Description
Summary:ABSTRACT Soluble conjugated polymeric nanoparticles were synthesized through Sonogashira polycondensation between different combinations of multifunctional alkynes and aryl halides in structurally well‐defined mesoporous reactors. The growth of the polymeric nanoparticles was controlled by the spatial confinement of the nanoreactors, giving conjugated polymeric nanoparticles with narrow size distribution centered at 5 nm. All the obtained polymers are freely soluble in common solvents and can be fabricated into thin film. Both of the solution and thin film prepared from these polymeric nanoparticles were highly fluorescent, endowing them potential applications in light emitting and other optoelectronic fields. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2016, 54, 2285–2290 Multifunctional alkynes and aryl halides are employed to Sonogashira polycondensation in confined nanoreactors, giving soluble conjugated microporous polymer nanoparticles with narrow size distribution. The growth of polymeric nanoparticles is controlled by these mesoporous nanoreactors as the palladium catalysts are embedded exclusively inside the internal channels. These nanoparticles have high solubility in common solvents and good processability to be fabricated into film. Both of the solution and film are highly fluorescent, endowing them potential applications in optoelectronic fields.
