| description | <p dir="ltr">In this work, 3,3′-sulfonylbis(7-(diethylamino)-2H-chromen-2-one), an effective fluorescent push-pull system, is synthesized and photophysically characterized. The donor-π–acceptor–π–donor (D–π–A–π–D) architecture of the push-pull system exhibits distinctive solvatochromic behavior that is controlled by the surrounding medium. The photophysical characteristics of the molecule were investigated in detail by means of computational and experimental techniques. A variety of solvents were used to record UV–Vis absorption and <u>fluorescence spectra</u>, which showed notable bathochromic alterations in response to increasing solvent polarity. The <u>fluorescence quantum yield</u> changed substantially with solvent polarity, indicating the maximum efficiency in nonpolar liquids. In order to forecast electronic transitions and improve the molecular shape, Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TD-DFT) simulations were used, offering insights into the ground and excited state behaviors. The study elucidates the relationship between solvent characteristics and the photophysical behavior of the bis-coumarinyl <u>sulfone</u>, offering valuable information for designing advanced fluorescent materials with adaptable photophysical properties.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Vibration Engineering & Technologies<br>License: <a href="https://creativecommons.org/licenses/by/4.0/deed.en" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s42417-024-01618-3" target="_blank">https://dx.doi.org/10.1007/s42417-024-01618-3</a></p> |
