Abstract
The
surface-mediated synthesis of ordered linear or zigzag polymers
on a highly oriented pyrolytic graphite surface was investigated either
at a solid/liquid interface or with moderate heating under low vacuum.
Scanning tunneling microscopy (STM) reveals the submolecular details
of the structure and growth dynamics of surface-confined one-dimensional
polymers. We discovered that the substituent and concentration of
monomers have a significant effect on the assembling structure of
the in-situ-synthesized one-dimensional polymer at the octanoic acid/graphite
interface
