Abstract

Guanine molecules adsorbed on the Au(111) surface at room temperature are observed to form a heterochiral phase consisting of two homochiral G-quartet networks (see image, left). By annealing the sample at 400 K the R and L homochiral G-quartet networks are found to irreversibly transform to a heterochiral G-quartet network including both R and L G-quartets in an equal amount (see image, right).
