Synthesis and photochromic properties of disulfide-1,3-diazabicyclo[3.1.0]hex-3-ene functionalized silver nanoparticles

The new 1,3-diazabicyclo[3.1.0]hex-3-ene derivative with disulfide bond to modify silver nanoparticle (AgNP) surface was synthesized. The photochromism of the packed ligand on AgNPs showed a pronounced bathochromic shift in the absorption band of the open ring photoisomers and also in the surface plasmon resonance absorption (SPRA) of AgNPs.
