Stereoisomerism‐controlled Packing in Ladder‐type Indacenodithieno[3,2‐b]thiophene Crystals

open access: yesAggregate
Stereochemistry is a potent way to direct the molecular packing in condensed phases. Here, we synthesized the enantiopure, racemic, and achiral isomers of p‐type small molecule, that is, indacenodithieno[3,2‐b]thiophene, to understand the impact of ...

A new bonded silica based on an amino acid derivative as a TLC stationary phase to solve nitrophenol structural isomerism and ibuprofen stereoisomerism

open access: yesFuture Journal of Pharmaceutical Sciences, 2020
Background Many amino acids and their derivatives have been used previously as chiral selectors in thin layer chromatography. Herein, we reported the synthesis, characterization, and chromatographic evaluation of a new modified stationary phase based on (

Alkali cation-π interactions in aqueous systems, modulating supramolecular stereoisomerism of nanoscopic metal-organic capsules

open access: yesNature Communications
Contrary to common chemical intuition, cation-π interactions can persist in polar, aqueous reaction solutions, rather than in dry non-coordinative solvent systems.
