J. Weckesser et al., Mesoscopic correlation of supramolecular chirality in one-dimensional hydrogen-bonded assemblies - art. no. 096101, PHYS REV L, 8709(9), 2001, pp. 6101
The ordering of 4-[trans-2-(pyrid-4-yl-vinyl)] benzoic acid, a two-dimensio
nal chiral species, was studied by scanning tunneling microscopy at noble m
etal surfaces. Homochiral molecules self-assemble in supramolecular chiral
hydrogen-bonded twin chains, which order in nanogratings where the supramol
ecular chirality is strictly correlated over the entire mum domains without
intimate molecular contact. Model simulations indicate that the underlying
mesoscopic chiral resolution is associated with twin chains acting as chir
oselective templates for transient molecular attachment, which process medi
ates the gratings' evolution.
