An Ultra-Long-Lived Triplet Excited State in Water at Room Temperature: Insights on the Molecular Design of Tridecafullerenes
(Angewandte Chemie International Edition, 2021-05-13)Suitably engineered molecular systems exhibiting triplet excited states with very long lifetimes are important for high-end applications in nonlinear optics, photocatalysis, or biomedicine. We report ... -
Autocatalytic photoinduced oxidative dehydrogenation of pyrido[2,3-d]pyrimidin-7(8H)-ones: synthesis of C5–C6 unsaturated systems with concomitant formation of a long-lived radical
(Organic Chemistry Frontiers, 2024, 11(1), 2024-01-07)5,6-Dihydropyrido[2,3-d]pyrimidin-7(8H)-ones are readily accessed by a variety of methods and are a good scaffold for the development of biologically active compounds. However, they are very reluctant ... -
Development of green/red-absorbing chromophores based on a coumarin scaffold that are useful as caging groups
(Journal of Organic Chemistry. Vol.82, n.10 (2017), p.5398-5408, 2017-05)We report the design, synthesis, and spectroscopic characterization of a series of push–pull chromophores based on a novel coumarin scaffold in which the carbonyl of the lactone function of the original ... -
Optical writing and reading with a photoactivatable carbazole
(Physical Chemistry Chemical Physics. Vol.17, n.17 (2015), p.11140-11143, 2015-03)The fluorescence of a carbazole chromophore can be activated irreversibly under optical control with the photoinduced opening of an oxazine ring. In proximity to silver nanoparticles, the quantum ...
