Decoding Carbon Dot Purity by Nuclear Magnetic Resonance

open access: yesAngewandte Chemie, EarlyView.
NMR spectroscopy tracks the removal of molecular and oligomeric impurities in carbon dots, enabling a (semi)quantitative evaluation of their purity through integrated peak analysis. ABSTRACT Carbon dots (CDs) have attracted increasing attention in recent years and have been widely explored in many fields.

Mapping the Reactivity of the C═C Bond of Cyclic Enol Ether Derivatives of Sugars: Nucleophilicity Parameters of Glycals

open access: yesAngewandte Chemie International Edition, EarlyView.
Endo or Exo? The first quantitative kinetic mapping of the nucleophilic reactivity of endo‐ and exo‐glycal compounds highlighted that endo‐glycals are typically 102 times less reactive than their corresponding parent cyclic enol ethers while exo‐glycals are 103 more nucleophilic. This experimental and computational structure–reactivity study highlights
