Abstract

Abstract Highly emissive inorganic–organic nanoparticles with core–shell structures are fabricated by a one-pot, surfactant-free hybridization process. The surfactant-free sol–gel reactions of tetraphenylethene-(TPE) and silole-functionalized siloxanes followed by reactions with tetraethoxysilane afford fluorescent silica nanoparticles FSNP-1 and FSNP-2, respectively. The FSNPs are uniformly sized, surface-charged and colloidally stable. The ...
