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 ...

New triphenylene derivatives 3 and 5, synthesized using a Suzuki-Miyaura coupling protocol and by a click reaction respectively, serve as potent chemosensors for various electron deficient nitroaromatic explosives, such as picric acid, trinitrotoluene, dinitrotoluene and dinitrobenzene. Derivative 5 exhibits a more sensitive response towards the nitroaromatics compared to derivative 3 due to it...

2,5-Diamino-1,4-benzoquinonediimine (DABQDI) derivatives possessing two electron-withdrawing aromatic N-substituents can potentially exhibit a zwitterionic ground state in lieu of the expected canonical structure. It was previously shown that use nitroaromatics groups (EWG) could yield quantitative formation tautomer DABQDI polar solvents, while mixture and forms present low polarity solvents. ...

The noble metal nanoparticles sandwiched between the stable inorganic core and thin polymer shell could not only enhance their stability, but also cut short diffusion route of outside reactants through toward encapsulated nanoparticles, which has drawn great attention. However, weak compatibility among core, shell, makes preparation metal-confined hybrid catalysts complicated, limits popular ap...
