Chiral Distortion of Confined Ice Oligomers (n= 5,6)


Ma, Haifeng; Ding, Yun; Iannuzzi, Marcella; Brugger, Thomas; Berner, Simon; Hutter, Jürg; Osterwalder, Jürg; Greber, Thomas (2012). Chiral Distortion of Confined Ice Oligomers (n= 5,6). Langmuir, 28(43):15246-15250.

Abstract

Ice nuclei have been studied on the hexagonal boron nitride nanomesh (h-BN/Rh(111)), a template with 2 nm wide molecule traps. Scanning tunneling microscopy shows confined clusters, where oligomers with three protrusions are particularly abundant. Together with local barrier height dI/dz maps, it is found that the dipoles of the water molecules arrange in a homodrome, which is consistent with density functional theory calculations. Hydrogen bonds toward the substrate identify h-BN/Rh(111) to be hydrophilic. The substrate distorts the hexamers (n = 6) and possibly pentamers (n = 5), where the experimentally observed footprints of the three protrusions appear more chiral than expected.
