Diarylethene-capped gold nanoparticles were synthesized by a self-assembled monolayer (SAM) technique and the photochemical behavior was studied. The average diameter of the particles was determined to be 1.1 nm from TEM image. The synthesized nanoparticles showed reversible photochromic reactivity regardless of the presence of the surface plasmon band.
Gold and silver nanoparticles capped with photochromic diarylethene ligands were prepared and their photochromic performance was investigated. Although the quenching of cyclization reactions by the metal particles took place to some extent, the diarylethene on the nanoparticles underwent reversible photochromic reactions by irradiation with UV and visible light.
