Mesoscopic correlation of supramolecular chirality in one-dimensional hydrogen-bonded assemblies - art. no. 096101

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.
