“…Similar results were reported after calcite electrodeposition in the presence of tartaric, maleic, and aspartic acid enantiomers [196]. Electrodeposition of copper oxide under the influence of tartaric acid enantiomers was found to create homochiral CuO films [197][198][199]. A strong indication that a chiral reconstruction of an inorganic surface occurred came from particle research.…”

With the adsorption of larger molecules being increasingly tackled by surface scientists, the aspect of chirality often plays a role. This paper gives a topical review of molecular chirality at surfaces and gives a phenomenological overview of different aspects of adsorption and self‐assembly of chiral and prochiral molecules and the principles of mirror‐symmetry breaking at a surface. After a brief introduction into the history of molecular chirality and the important role it played for understanding the spatial structure of molecules, definitions of chirality are presented. Topics treated here are principle ways to create single chiral adsorbates, chiral ensembles, and monolayers by achiral molecules, adsorption of intrinsically chiral molecules at achiral and chiral surfaces, long‐range symmetry breaking in two‐dimensional (2D) crystals due to additional chiral bias, chiral restructuring of solid surfaces under the influence of chiral molecules, switching the handedness of adsorbates, and chirality at the liquid/air interface. An outlook onto further potential research directions and recommendations for further reading, including nonsurface‐related sources of chiral topics completes this paper.

“…Understanding the mechanism of electrochemical reactions is important from the basic science point of view, as well as for the development of electrochemical applications, such as batteries, solar and fuel cells, etc [1][2][3][4][5][6]. It is also important in studies of the corrosion and wear of copper brushes in electrical motors [7].…”

A novel electrochemical setup has been developed for soft x-ray absorption studies of the electronic structure of electrode materials during electrochemical cycling. In this communication we illustrate the operation of the cell with a study of the corrosion behavior of copper in aqueous NaHCO 3 solution via the electrochemically induced changes of its electronic structure. This development opens the 2 way for in situ investigations of electrochemical processes, photovoltaics, batteries, fuel cells, water splitting, corrosion, electrodeposition, and a variety of important biological processes.

“…In recent years, much effort has been expended on researching methods of fabricating nanoscale chiral surfaces, in many cases with the goal of improving enantioselectivity in asymmetric induction 6 , high-performance liquid chromatography 7,8 and high-sensitivity chirality detection 9,10 . Fabrication techniques include cleaving metal surfaces along low-symmetry planes 11 , adsorption of chiral molecules onto metal surfaces [12][13][14] , electrodeposition 15 , molecular imprinting [16][17][18] , glancing-angle deposition 19 and employment of metal-organic frameworks 20 . Liquid crystal (LC) systems have recently emerged as a promising class of materials exhibiting chiral interface effects, since they readily self-assemble into complex chiral structures in response to little more than appropriate sequences of changing temperature 21 .…”

Diastereomeric liquid crystal domains at the mesoscale

et al. 2015

In many technologies used to achieve separation of enantiomers, chiral selectors are designed to display differential affinity for the two enantiomers of a chiral compound. Such complexes are diastereomeric, differing in structure and free energy for the two enantiomers and enabling chiral discrimination. Here we present evidence for strong diastereomeric interaction effects at the mesoscale, manifested in chiral liquid crystal guest materials confined in a chiral, nanoporous network of semi-crystalline helical nanofilaments. The nanoporous host is itself an assembly of achiral, bent-core liquid crystal molecules that phase-separate into a conglomerate of 100 micron-scale, helical nanofilament domains that differ in structure only in the handedness of their homogeneous chirality. With the inclusion of a homochiral guest liquid crystal, these enantiomeric domains become diastereomeric, exhibiting unexpected and markedly different mesoscale structures and orientation transitions producing optical effects in which chirality has a dominant role.
