The propeller-shaped perylene diimide (PDI) hexamers invert their helical twist (propeller chirality) depending on the solvent, leading to changes in both the sign and intensity of circularly ...

Scientists have discovered a new way to create one hand of a chiral molecule by using a mechanical bond as a catalyst. Scientists at the University of Southampton have discovered a new way to create ...

Cage-shaped molecule that changes from left-handed to right-handed when a metal ion enters its inner cavity. The conversion speed varies up to 1000 times depending on the size of the metal ion (K +, ...

Chemists fill a major gap in origin-of-life theories. Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions, akin to the left ...

Some molecules exist in two forms, such that their structures and their mirror images are not superimposable, like our left and right hands. As a result of their asymmetry, these molecules exhibit a ...

In nature, the concept of chirality or "handedness" is fundamental to life itself, just as our left and right hands are mirror images that cannot be overlapped perfectly. Molecular handedness is ...

A research group at The University of Tokyo has discovered a new principle by which helical chiral molecules acquire spin through molecular vibrations, enabling them to adhere to magnets. Until now, ...

Chemists at UC Davis are using catalysts (shown in gray spheres) to make organic compounds (blue sticks) with a specific chirality, or “handedness.” Most biological molecules are chiral, including ...

Like carbon and silicon, germanium’s lighter brethren on the periodic table, the metalloid can bond to four different groups, forming a chiral, tetrahedral molecule. Researchers at Nankai University ...
