Synthesis and fluorosolvatochromism of 3-arylnaphtho[1,2-b]quinolizinium derivatives

Beilstein Journal of Organic Chemistry, 2016
Cationic biaryl derivatives were synthesized by Suzuki–Miyaura coupling of 3-bromonaphtho[1,2-b]quinolizinium bromide with arylboronic acids. The resulting cationic biaryl derivatives exhibit pronounced fluorosolvatochromic properties.

The capacitance and electron transfer of 3D-printed graphene electrodes are dramatically influenced by the type of solvent used for pre-treatment

Electrochemistry Communications, 2019
3D-printing (or additive manufacturing) is presently an emerging technology that promises to reshape traditional manufacturing processes. The electrochemistry field can certainly take advantage of this fabrication tool for sensing and energy-related ...

Preferential Solvation of Zwitterionic Benzo-[f]-Quinolinium Ylids in Binary Solvent Mixtures: Spectral Study and Quantum Chemical Calculations

Molecules
Three derivatives of benzo-[f]-quinolinium ylids, which all underwent an intermolecular charge transfer process, were used as solvatochromic indicators to study the specific solvent–solute interactions in binary mixtures of protic–aprotic solvents with ...

Solvent Effects on the Conformational Preferences of 2,6‐Pyridylcarboxamide Foldamers

Chemistry – A European Journal, EarlyView.
The marked effect of organic solvents and water/methanol mixtures on the conformational preferences of a soluble chiral foldamer has been established in a diverse array of seventeen distinct environments. ABSTRACT The marked influence of organic solvents and water on the conformational preferences of a chiral, soluble 2,6‐pyridylcarboxamide foldamer ...

Mechanistic Insights Into Luminol Chemiexcitation: The Role of the Amide Carbonyls

Chemistry – A European Journal, EarlyView.
By means of quantum‐chemical calculations, we demonstrate that the 1,2‐dioxin ring forms following nitrogen release from parent luminol. We also identify alkoxide groups derived from the amide carbonyls of luminol as key enhancers of the chemiexcitation yield.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
