STM observations of the first polymerization steps between hexahydroxy-tri-phenylene and benzene-di-boronic acid molecules

► Observation of the first polymerization steps between benzene-diboronic acid (BDBA) and hexahydroxy-triphenylene (HHTP) molecules. ► STM observations of different HHTP networks on Ag(111). ► STM observations of the oligomer formation. ► Investigations of the first covalent organic structures. ► Vertical manipulation of HHTP using the STM tip.
