The central chirality of simple amino alcohols was amplified by binding to a dynamically axially chiral biphenol receptor and expressed as supramolecular chirality by effecting a change from a nematic to a cholesteric liquid crystalline phase.

A chiral pseudo-C(3)-symmetric titanium triflate that employs the point chirality of a single stereogenic centre to control the propeller chirality of its aryl rings has been used to catalyse an asymmetric sulfoxidation reaction.

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...

Chemical vapor deposition (CVD) growth is regarded as the most promising method for realizing structure-specific single-walled carbon nanotube (SWNT) growth. In the past 20 years, many efforts dedicated to chirality-selective SWNT growth using various strategies have been reported. However, normal CVD growth under constant conditions could not fully optimize the chirality because the randomly f...

The electron diffraction pattern of a SWCNT has an equatorial line L0 and several layer lines L1, L2, L2, etc.. The distance between the layer lines and the equatorial line can be written as d1, d2, d3, etc.. The relationship between the chiral angle of a CNT and d1, d2, and d3 in its electron diffraction pattern has been given as formula (2) in Reference 27. We take SWCNT1 in S1 and SWCNT2 in ...

Chirality is a critical property of amino acids that form proteins, the building blocks of life, and of DNA, which encodes the genetic traits passed from one generation to the next. Furthermore, chirality can be observed throughout nature in objects ranging from spiral seashells to the human hands. If an object and its mirror image are nonsuperimposable, then they have the property of chirality...

Supramolecular chirality of crystals which display chirality only in the solid state was for the first time measured by diffuse reflectance circular dichroism (DRCD) spectroscopy for sublimable 1 : 1 pyrene (PYR)-p-benzoquinone (Q) complex, and its integrity was proved.

Chirality plays a significant role in the physical properties and biological functions of many biological materials, e.g., climbing tendrils and twisted leaves, which exhibit chiral growth. However, the mechanisms underlying the chiral growth of biological materials remain unclear. In this paper, we investigate how the Towel Gourd tendrils achieve their chiral growth. Our experiments reveal tha...

The paper reviews recent progress on chiral nanocrystal assemblies with induced optical chirality and related circular dichroism. Many natural molecules and biomolecules are chiral and exhibit remarkably strong optical chirality (circular dichroism) due to their amazingly uniform atomic composition in a large ensemble. It is challenging to realize artificial nanoscale systems with optical chira...
