Chirally locked and dynamic bis-perylene diimide macrocycles with multiple sources of chirality [PDF]

open access: yesCommunications Chemistry
Chiral organic materials show great promise in optoelectronics, sensing and catalysis. Among those, macrocycles are of great interest due to their preorganisation and potential amplification of chiroptical properties.

Chirality-Selective Transport of Benzene Molecules on Carbon Nanotubes

open access: yes, 2020
Using molecular dynamics simulations, we predict an effect of chirality on the conduction of benzene molecules along the surface of carbon nanotubes (CNTs) subjected to a thermal gradient. The group drift velocity of the molecules was found to be maximal

Chiral Bromonium Salt (Hypervalent Bromine(III)) with N-Nitrosamine as a Halogen-Bonding Bifunctional Catalyst

open access: yesMolecules, 2023
There has been a great focus on halogen-bonding as a unique interaction between electron-deficient halogen atoms with Lewis basic moieties. Although the application of halogen-bonded atoms in organic chemistry has been eagerly researched in these decades,

Molecular chirality and chiral parameters [PDF]

open access: yesReviews of Modern Physics, 1999
The fundamental issues of symmetry related to chirality are discussed and applied to simple situations relevant to liquid crystals. We show that any chiral measure of a geometric object is a pseudoscalar (invariant under proper rotations but changing sign under improper rotations) and must involve three-point correlations which only come into play when

Development of a novel light-up probe for detection of G-quadruplexes in stress granules

open access: yesScientific Reports, 2022
G-quadruplexes (G4s) regulate various biological processes in cells. However, cellular imaging of dynamically forming G4s in biomolecular condensates using small molecules has been poorly investigated. Herein, we present a fluorescent light-up probe with
