On January 13, 2021, Padgaonkar, Suyog; Eckdahl, Christopher T.; Sowa, Jakub K.; Lopez-Arteaga, Rafael; Westmoreland, Dana E.; Woods, Eliot F.; Irgen-Gioro, Shawn; Nagasing, Benjamin; Seideman, Tamar; Hersam, Mark C.; Kalow, Julia A.; Weiss, Emily A. published an article.Safety of Diethyl succinate The title of the article was Light-Triggered Switching of Quantum Dot Photoluminescence through Excited-State Electron Transfer to Surface-Bound Photochromic Molecules. And the article contained the following:
This paper describes reversible “on-off” switching of the photoluminescence (PL) intensity of CdSe quantum dots (QDs), mediated by photochromic furylfulgide carboxylate (FFC) mols. chemisorbed to the surfaces of the QDs. Repeated cycles of UV and visible illumination switch the FFC between “closed” and “open” isomers. Reversible switching of the QDs’ PL intensity by >80% is enabled by different rates and yields of PL-quenching photoinduced electron transfer (PET) from the QDs to the resp. isomers. This difference is consistent with cyclic voltammetry measurements and d. functional calculations of the isomers’ frontier orbital energies. This work demonstrates fatigue-resistant modulation of the PL of a QD-mol. complex through remote control of PET. Such control potentially enables applications, such as all-optical memory, sensing, and imaging, that benefit from a fast, tunable, and reversible response to light stimuli. The experimental process involved the reaction of Diethyl succinate(cas: 123-25-1).Safety of Diethyl succinate
