Enhancing Ultraviolet Stability and Operational Durability of Perovskite Photodetectors by Incorporating Chlorine into Thermally-Switchable Tautomeric Passivators [PDF]

open access: yesNano-Micro Letters
Highlights The tautomeric UV absorbers (UV320/UV327) in perovskites reveal keto–enol tautomerism, generating extra –C=O groups to enhance defect passivation.

Putting the squeeze on valence tautomerism in cobalt-dioxolene complexes [PDF]

open access: yesNature Communications
Molecules that can reversibly switch between electronic states under an external stimulus are of interest to numerous applications. Complexes of open shell metal ions with redox active ligands undergo valence tautomerism, resulting in magnetic, colour ...

Comparative Review of O,O′-, N,O-, and N,N′-Bidentate Ligands: Structural and Electronic Properties of β-Diketones, Enaminones, and β-Diketiminates [PDF]

open access: yesMolecules
Bidentate ligands, derived from the 1,3-dicarbonyl framework, play a central role in coordination chemistry, catalysis, and materials science due to their tuneable donor properties and structural versatility.

Tautomerism in Neutral Histidine

open access: yesAngewandte Chemie - International Edition, 2014
AbstractHistidine is an important natural amino acid, involved in many relevant biological processes, which, because of its physical properties, proved difficult to characterize experimentally in its neutral form. In this work, neutral histidine has been generated in the gas phase by laser ablation of solid samples and its NεH tautomeric form unraveled

Keto-Enol Tautomerism in Passerini and Ugi Adducts

open access: yesMolecules, 2021
The use of arylglyoxal as starting material in Passerini and Ugi reactions affords β-ketoamides. This has allowed to study keto-enol tautomerism in these systems and assess the way in which the presence of acyloxy or aminoacyl groups bound to the C2 ...

Azo-hydrazone tautomerism of aryl azo pyridone dyes [PDF]

open access: yesHemijska Industrija, 2013
In the last three or four decades disperse dyes derived from pyridones (in particular azo pyridone dyes) have gained in importance, and are widely used in various fields.

Products of Photo- and Thermochemical Rearrangement of 19-Membered di-tert-Butyl-Azoxybenzocrown

open access: yesMolecules, 2022
The preparation and characterization of products of the photochemical and thermochemical rearrangements of 19-membered azoxybenzocrowns with two, bulky, tert-butyl substituents in benzene rings in the para positions to oligooxyethylene fragments (meta ...

Geometry, tautomerism and non-covalent interactions of the drug halofuginone with the carbon-nanotube and γ-Fe2O3 nanoparticles: A DFT study [PDF]

open access: yesJournal of the Serbian Chemical Society, 2018
Halofuginone is a potential anti-malarial drug, which could exist as three possible tautomers. Herein, using density functional theory (DFT), and handling the solvent effects with the PCM model, the tautomerism of halofuginone was investigated ...
