Hydrogen-Bonded Encapsulation Complexes in Protic Solvents
, 2016 We describe here the behavior of the hydrogen-bonded capsule 1·1 and its complexes in protic solvents. The kinetics and thermodynamics of the encapsulation process were determined through conventional 1H NMR methods.

Unprecedented high fluorescence anisotropy in protic solvents: hydrogen bond induced solvent caging?
, 2016 Atypical high fluorescence anisotropy has been revealed in protic solvents for excited state intramolecular proton transfer (ESIPT) prone 3-hydroxyflavone and some of its hydroxy derivatives. In non-protic solvents, however, the anisotropy values are low.

Epimerization of ergot alkaloids in feed
Heliyon, 2020 Chronic intake of cereals contaminated with ergot alkaloids can cause ergotism and result in the loss of toes and fingers or even death. Today, due to common risk management practices, ergotism is rare as a human disease but remains a problem in ...

Programmable Functional Silicification of DNA Origami Nanostructures
Advanced Materials, EarlyView.This work introduces additional functionality into silica‐coated DNA origami nanostructures using non‐standard silica precursors. A fluorescent precursor enables enhanced intracellular tracking, while a disulfide‐containing reagent yields redox‐responsive, degradable silica coatings.

Angewandte Chemie, EarlyView.Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...
