Проведено сравнительное спектрально-кинетическое исследование взаимодействия тиолзамещенных молекул диарилэтена и спирооксазина с наночастицами графена и нанопластинками оксида графена. Выявлены различия в фотохромных превращениях соединений, контактирующих с поверхностью углеродных наночастиц в зависимости от структуры соединений и природы наночастиц, свидетельствующие о химическом и физическом взаимодействии молекул фотохромных соединений с поверхностными группами углеродных наноструктур.
The results of studies of the spectral-kinetic (absorption and fluorescent) characteristics of the polymer nanospheres created by us (containing luminescent inorganic CdSe/ZnS quantum dots and photochromic diarylethene molecules) incorporated into a polymer film are presented.
A reversible modulation of the fluorescence intensity of quantum dots, caused by the photoisomerization of diarylethene molecules, was found. It is shown that nanospheres in polymer matrices exhibit higher efficiencies of both photoinduced modulation of QD radiation and Förster resonance energy transfer (FRET) from QDs to the cyclic isomer of DAE as compared to solutions.
The results can be used, for example, to create luminescent photocontrolled panels based on films containing fluorescent nanoparticles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
