Recognition of quaternary ammonium cations by calix[4]arene derivatives supported on gold nanoparticles.
Calix[4]arene derivatives supported on monolayer protected gold clusters show a remarkable enhanced binding efficiency towards quaternary ammonium salts in homogeneous solution of apolar solvents with respect to the corresponding unsupported hosts.
