STM insight into hydrogen-bonded bicomponent 1D supramolecular polymers with controlled geometries at the liquid-solid interface.

ABSTRACT

Bicomponent supramolecular polymers, consisting of two alternating molecules bridged through six H-bonds, are observed by STM at the solid-liquid interface. Control of the geometry of the 1D architecture was obtained by using two different connecting molecules with different conformational rigidity, affording either linear (see picture, left) or zigzag (right) motifs.
