Abstract

original image

Through interactions between sulfonic groups of the water-soluble Au cluster C and imino groups of a poly(ethylenimine) layer B on a mica surface A, this cluster could be attached for the first time in a largely ordered form as a monolayer. Now, for example, electronic transitions of quantum dots (cluster cores) separated by ligand shells can be investigated.
