Abstract:

The monomer 3-hexadecyl pyrrole was polymerized at the gasliquid interface. Monomer and polymer were transferred from the interface to MoS2 for investigation by STM after annealing. Monolayers of monomer and polymer were highly ordered showing orientational and positional correlation of alkyl side chains. Polymer monolayers showed increased side chain packing density and side chain orientation more orthogonal to the surface. Polymer multilayers showed disorder, revealing connectivity and curvature of polymer chains. Conformations of polymer chains suggest growth in a parallel fashion at the gasliquid interface.
