Covalent Interlinking of an Aldehyde and an Amine on a Au(111) Surface in Ultrahigh Vacuum

Abstract

Getting a reaction: A condensation reaction occurs between a dialdehyde and an amine coadsorbed on a Au(111) surface in an ultrahigh vacuum. The self-assembled structures formed by the diimine reaction product on the surface have been investigated by scanning tunneling microscopy (see image). A solvent-free reaction path is proposed from DFT calculations.
