Abstract: The direct polymerization via irreversible C-C coupling on inert substrates will give access to new low-dimensional advanced functional materials and simplify their industrial fabrication. In this work, we present our initial results in the application of Glaser coupling to the direct on-surface polymerization of a model diacetylene compound at the solid-vapor interface. The self-assembly of the monomer and polymerization products was characterized using scanning tunneling microscopy (STM). In addition, selected optical properties and the electronic structure of all compounds were investigated.
