The thermodynamic and kinetic stability of three structurally related monolayer-protected gold clusters have been systematically investigated, revealing that the nanoparticles display significantly different stability against thermo- and cyanide-induced decomposition and external thiol agents.
Several 16-crown-5 derivatives having an electron-donating sidearm were newly prepared and their stability constants toward Na+ and K+ were measured. The difference in the position of the sidearm was disclosed to change remarkably the complexation property of such type of compounds.
