Abstract

We have demonstrated a cavity formation with molecular precision in an ordered film of 4,4′-biphenyl dicarboxylic acid (BDA) molecules on the Au(111) surface using scanning tunneling microscopy. The BDA molecules are removed through the injection of tunneling electrons into the molecule, which excite the vibrational mode of the BDA molecule to cleave the hydrogen bonding between carboxyl groups. The structures have molecular-scale sharp edges and can be used as cavities for the investigation of a host - guest architecture on surfaces.
