Heterogenisation of a carbonylation catalyst on dispersible microporous polymer nanoparticles

Palladium nanoparticles supported on a triptycene-based microporous polymer: highly active catalysts for CO oxidation.

Pd nanoparticles were well dispersed on a new triptycene-based microporous polymer support by the gas bubbling-assisted membrane reduction (GBMR) method. The stability of Pd nanoparticles is improved by the porous support, and the materials show excellent performance for CO oxidation.

Thin film fabricated from solution-dispersible porous hyperbranched conjugated polymer nanoparticles without surfactants.

Porous hyperbranched conjugated polymer nanoparticles with an average particle size of 20-60 nm and a specific surface area of 225 m(2) g(-1) have been prepared through Suzuki polymerization in a miniemulsion, which could be stably dispersed in common organic solvents after complete removal of surfactants. Furthermore, a simple spin-coating method for the preparation of homogeneous transparent ...

Fluorescent nanoparticles based on a microporous organic polymer network: fabrication and efficient energy transfer to surface-bound dyes.

Well-defined nanoparticles composed of a tetraphenylmethane-based microporous polymer network with an average particle diameter of 30-60 nm were fabricated by a miniemulsion polymerization technique. Strong green emission was observed and efficient excitation energy transfer from nanoparticles to surface-bound dye molecules was explored.

Water-dispersible TiO2 nanoparticles via a biphasic solvothermal reaction method

A biphasic solvothermal reaction method has been used for the synthesis of TiO2 nanoparticles (NPs). In this method, hydrolysis and nucleation occur at the interface of organic phase (titanium (IV) n-propoxide and stearic acid dissolved in toluene) and water phase (tert-butylamine dissolved in water) resulting in the nucleation of the stearic acid-capped TiO2 NPs. These NPs are hydrophilic due ...
