DFT, TDDFT, UV-Vis and electrochemical investigation of chalcone sulfonate esters: Structure-property relationships and substituent effects.

Chalcone sulfonate esters constitute an emerging class of hybrid molecules in which the conjugated chalcone framework is combined with an arylsulfonyloxy substituent, providing opportunities to modulate their electronic and electrochemical properties. In this study, three chalcone sulfonate esters were investigated usi...

Synthesis and multimodal characterization of flavonols: electrochemical, spectroscopic, and DFT approaches.

Five flavonols bearing electron-donating and electron-withdrawing substituents were synthesized and characterized by NMR spectroscopy, mass spectrometry, UV-Vis spectroscopy, and cyclic voltammetry. Density functional theory (DFT) and time-dependent DFT (TDDFT) calculations were performed to investigate their molecular...
