Abstract

The combination of metal nanoparticles and molecular photo- or electroactive components at the nanoscale opens up new avenues of nanoassemblies with unique properties. In this study, hybrid nanoassemblies with metal nanoparticle monolayer and polymer nanosheets containing ruthenium (II) tris(2,2bipyridine) derivative (Ru(bpy)₃^2- ) were fabricated by the Langmuir-Blodgett technique. Gold and silver nanoparticles were prepared by citrate reduction method and immobilized onto amino pendant copolymer (p(DDA/DADOO)) nanosheets through electrostatic interaction. Emission intensity from ruthenium complex decreased in the presence of gold nanoparticles, whereas the intensity was enhanced in the presence of silver nanoparticles. Optical oxygen sensing properties of Ru(dpphen)₃ ²⁺silver nanoparticle hybrid nanoassemblies will be also discussed.
