Ullmann coupling is one of the most frequently employed methodologies for producing π-conjugated surface-confined polymers. One unfortunate side product reaction creation metal halide islands formed from liberated halogen atoms. Following reaction, these can account a large proportion substrate surface area and thus inhibit domain growth effectively poison catalyst. Here, we describe an efficient reliable methodology removing byproduct at room temperature by exposure to beam atomic hydrogen;...
An activated reaction can lead to a diversity of intermolecular bonding motifs through partially-reacted molecules.
A detailed understanding of the reaction a range molecules on surfaces will be key to developing targeted strategies for on-surface synthesis. Here, we studied deprotonation and decarboxylation reactions 3,5-pyridinedicarboxylic acid (PDC) Cu(111) using synchrotron radiation photoelectron spectroscopy (SRPES), near-edge X-ray absorption fine structure (NEXAFS) spectroscopy, density functional theory (DFT). PDC partially deprotonates upon deposition at room temperature adsorbs with plane its...
The surface-assisted reaction of rationally designed organic precursors is an emerging approach toward fabricating atomically precise nanostructures. Recently, on-surface decarboxylation has attracted attention due to its volatile by-products, which tend leave the surface during means only desired products are retained on surface. However, in addition acting as reactive site, carboxylic acid groups play a vital role adsorption configuration small-molecule molecular and therefore pathways....
On-surface synthesis of conjugated polymers is made challenging by the need to promote desired reaction while preventing or minimizing unwanted ancillary reactions that compromise product integrity. We perform a comprehensive study 2,5-dichloro-3,4-ethylenedioxythiophene on coinage metal surfaces, and demonstrate only Ag(111) can we obtain planar polymer product, polyethylenedioxythiophene (PEDOT).
