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.

“…[41][42][43][44][45][46][47] Up to now, the inclusion complex formation of azobenzenecontaining compounds and beta-cyclodextrin (beta-CD)/alphacyclodextrin at the air/water interface was investigated and characterized. [48][49][50][51][52] It can be interesting that a combination of GO-based composites self-assembly lms involved in hostguest interactions via beta-CD and azobenzene segments by Langmuir technique should be particularly advantageous due to excellent molecular recognition, moderate self-assembled nanostructures, and designed self-assembly models. Thus, aqueous solutions of two soluble azobenzene-containing compounds (abbreviated as N-Azo and PAA-Azo) as subphase solutions have been designed and chosen for the preparation of composite lms.…”

“…Bolaamphiphiles, which include two functional headgroups generally connected by some alkyl chains [1][2][3][4][5][6][7], have attracted much attention due to their special chemical and interfacial behaviors in different self-assembled nanostructures [8][9][10]. Different from typical amphiphilic compounds, bola-type molecules demonstrate changeable conformations at different interfacial situations [11][12][13].…”

“…These properties make them extremely suitable for applications in in nanotechnology, electronics, and gene and drug delivery [14][15][16][17][18]. For example, Lin et al reported the preparation of a dual-responsive bola-type supramolecular amphiphile via complexation between pillar [5]arene and bolaform naphthalimide, which demonstrated good drug-loading efficiency and obvious improved anticancer properties [15].…”

The design and preparation of functional bolaamphiphile-based composite films are of key importance for application in a wide variety of fields. This study demonstrates a new approach to constructing composite films by the Langmuir-Blodgett (LB) method using a fluorine-containing bola-type diacid derivative with different metal ions. The bola-type molecule we used could be spread on water surfaces and metal ion subphases to fabricate various nanostructured ultrathin films. The obtained data demonstrated that the employed metal ions, including Ag(I), Cu(II), and Eu(III) ions in subphase solutions, can regulate the organized molecular stacking and form interfacial nanostructures deposited in LB films. It was found that the interfacial coordinating interactions can easily occur between carboxyl groups in a molecular skeleton with metal ions in the formed composite films. The formation of composite films was confirmed by changes in the surface pressure-area isotherms, morphologies, and spectra of the transferred LB films. While various research works have achieved the regulation of functions and nanostructures of sophisticated bola-type compounds, we here demonstrate a simple routine to modulate the nanostructures and organized packing of bola-type compounds composite films by changing the metal ions in subphase solutions.
