Chiral selection by interfacial shearing of self-assembled achiral molecules.

چکیده
We report a novel phenomenon of chiral selection in self-assembled condensates of achiral amphiphiles. The handedness of chiral textures, reproducing the collective rotational component of the molecular orientation inside submillimeter circular domains, is correlated with the sign of a vortical stirring in the aqueous subphase. We propose an explanation based on the distinctive kinetics of topological defect annihilation during domain coalescence at the initial coarsening stage of a phase-separating monolayer.

Self-assembled chiral superstructures composed of rigid achiral molecules and molecular scale chiral induction by dopants.
We explore the phase behavior of a rigid achiral bent-core model system. Nematic and smectic phases form at higher densities, whereas micelles and columns composed of chiral clusters of these molecules self-assemble at lower densities. No nucleation mechanism requiring transient chirality is possible in the formation of these chiral superstructures due to the rigid achiral nature of the substit...
متن کاملAffecting surface chirality via multicomponent adsorption of chiral and achiral molecules.
Here we report on the apparent reduction in surface chirality upon co-assembling a chiral and achiral molecule into a physisorbed self-assembled monolayer at the liquid/solid interface as revealed by scanning tunneling microscopy (STM). Chiral OPV with achiral thymine gives rise to surface-confined supramolecular diastereomers.
متن کاملOptical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods
An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...
متن کاملStirring competes with chemical induction in chiral selection of Langmuir monolayer domains
Chirality, the absence of mirror symmetry, can be equally invoked in relation to physical forces and chemical induction processes, yet a competition between these two types of influences is rarely reported. Here, we employ Langmuir monolayers of azobenzene surfactants as a prototypical self-assembled two-dimensional system in which chiral selection is controlled by the combined independent acti...
متن کاملChiral uranyl-organic compounds assembled with achiral furandicarboxylic acid by spontaneous resolution.
Influenced by different cations in the self-assembly of chiral units, achiral (UOC-NH4, UOC-Ca) and chiral (UOC-Na) uranyl-organic compounds were obtained from achiral reactants. The photocatalytic activity of UOC-Na was also investigated.
