Abstract

Sufficiently dense films of cerium oxide nanocrystals modified with decanoic acid, with sizes of ˜9 nm, were fabricated on the surface by modifying a silicon substrate with 3,4-dihydroxyhydrocinnamic acid, where catechol group lied at the top. By doing this, no further pretreatment for the modified cerium oxide nanocrystals is required to fix them chemically on the substrate. Selective adhesion between nanocyrstals and the substrate for the two-dimensional assembly can be attributed to the chemical bonding formed by on-site ligand exchange between carboxyl and catechol groups.
