Nov 12, 2019 · Easily accessible green-light activatable (>500 nm) photocages based on red-shifted, π-extended coumarin scaffolds are developed with uncaging efficiencies similar to …

Jan 16, 2025 · We demonstrate UV-emitting films of 2,5-diphenyloxazole (PPO) sensitised by 3,3′-carbonylbis (7-diethylaminocoumarin) (CBDAC), prepared by simple drop casting with rapid …

In this work, we have studied the effects of chain length and the head group of different cationic surfactants on the photophysics of an anionic dye, 7- (diethylamino)coumarin-3-carboxylic acid …

Aug 1, 2001 · This study shows that several coumarin or ketocoumarin/additives combinations (bisimidazole derivative, mercaptobenzoxazole, titanocene, oxime ester) are able to initiate …

Here we achieve a record-high TTA-UC efficiency of 20.3% among 100% maximum by employing a ketocoumarin derivative as a triplet sensitizer, which shows strong visible absorption, weak …

Apr 28, 2020 · In this study, eight coumarins (coumarins 1 – 8) are proposed as near-UV and blue light sensitive photoinitiators/photosensitizers for the cationic polymerization (CP) of …

Coumarin (/ ˈ k uː m ər ɪ n /) or 2H-chromen-2-one is an aromatic organic chemical compound with formula C 9 H 6 O 2. Its molecule can be described as a benzene molecule with two …

Here, we critically review the actual state of the art on natural and synthetic coumarins, focusing on the biological activity, structure–activity relationships (SARs), pharmacokinetics (PKs) and …

Jun 1, 2022 · Since DFT and TD-DFT techniques are critical in getting the desired photophysical characteristics of coumarin dyes before synthesis, this review also provides a glimpse of the …
