WebSep 5, 2024 · Chirality means handedness. It is exhibited by chiral molecules. They exist in pairs of stereoisomers. These are non-superimposable mirror images of each other. They do not have a plane of symmetry. They can rotate plane-polarized light and are optically active. Chirality is a property of molecules. WebChirality has been reported to play an important role in controlling and mediating the self-assembly of gels. There have been a few reports on molecular chirality–regulated tuning of gelation and nanostructures. Wu et al. designed two types of chiral gelators that were responsive to enantiomeric purity and they found that chiral gelators normally self …
