Развитие органической электроники стимулирует поиск новых материалов. Приоритетной задачей является нахождение соединений, обладающих высокой яркостью, эффективностью и стабильностью свечения. Кумариновые производные рассматриваются как перспективные кандидаты для решения этой задачи. Представлены результаты исследования органических светоизлучающих диодов (Organic Light-Emitting Diode, OLED), в эмиссионном слое которых использован ряд кумариновых красителей с выраженными донорно-акцепторными свойствами. Исследовано влияние структуры синтезированных молекул на фотофизические характеристики, а также на эффективность излучения светодиодов на их основе.</p></sec><sec><title>   Метод</title><p>   Метод. Синтезирована серия органических соединений кумаринового ряда: (Е)-3-(3-(антрацен-9-ил)акрилоил)кумарин (соединение 1), 4-гидрокси-3-(5-(4-метоксифенил)-1-(п-толил)-4,5-дигидро-1Н-пиразол-3-ил)кумарин (соединение 2), 3-(1-ацетил-5-(4-метоксифенил)-4,5-дигидро-1Н-пиразол-3-ил)-4-гидроксикумарин (соединение 3), этил 7-(диэтиламино)кумарин-3-карбоксилат (соединение 4), а также известный лазерный краситель Кумарин 6 (3-(бензо[d]тиазол-2-ил)-7-(диэтиламино)кумарин) (соединение Cou), используемый в качестве эталонного соединения. Светодиоды были изготовлены методом термического напыления в вакууме и методом центрифугирования. Исследование спектров флуоресценции и электролюминесценции проводилось при помощи спектрометра Ocean Optics Maya 200 PRO. Для получения кривых затухания люминесценции применен фотоэлектронный умножитель PicoQuant PMA-C 192-N-M.</p></sec><sec><title>   Основные результаты</title><p>   Основные результаты. Показано, что спектральные данные (поглощение, фотолюминесценция), а также время-разрешенные измерения (время затухания флуоресценции) указывают на ключевую роль донорно-акцепторных взаимодействий, а также пространственных эффектов в формировании электронных переходов. Вольт-амперные характеристики подтвердили наличие режимов проводимости, ограниченной пространственным зарядом, и проводимости, ограниченной процессамизахвата носителей. Изучение вольт-яркостных характеристик показало, что соединение 2 демонстрирует яркость, сопоставимую с соединением Cou, что делает его наиболее перспективным для дальнейшей оптимизации органических светоизлучающих диодов. Обнаружено, что соединение 4 в составе светодиода обеспечивает белое излучение с координатами цветности, близкими к дневному свету, что делает потенциально возможным его практическое применение в осветительных системах.</p></sec><sec><title>   Обсуждение</title><p>   Обсуждение. Полученные данные подтверждают влияние донорно-акцепторных взаимодействий на свойства кумаринов. Степень сопряжения донорных и акцепторных фрагментов напрямую определяют спектральные сдвиги в спектрах поглощения и флуоресценции. Высокая яркость светодиодов на основе соединения 2, сопоставимая с соединением Cou, обусловлена его эффективной донорно-акцепторной системой, оптимизирующей внутримолекулярный перенос заряда и понижающей вероятность безызлучательных переходов. Напротив, ацетильная группа в соединении 3 нарушает конъюгацию, приводя к низкой яркости и малому времени жизни флуоресценции (1,7 нс) из-за безызлучательной релаксации. Способность соединения 4 обеспечивать в диодах белое излучение (цветовая температура около 6410 К, близка к дневному свету) связана с вкладом электронного транспортного слоя в спектр излучения.</p></sec></abstract><trans-abstract xml:lang="en"><p>   The development of organic electronics stimulates the search for new materials. The priority task is to find compounds with high brightness, efficiency and stability of luminescence. Coumarin derivatives are considered as promising candidates for solving this problem. This paper presents the results of a study of organic light-emitting diodes in the emission layer of which a number of coumarin dyes with pronounced donor-acceptor properties are used.</p><p>   The aim of the study was to identify the influence of the structure of synthesized molecules on the photophysical characteristics as well as on the emission efficiency of LEDs based on them.</p><p>   A series of organic compounds of the coumarin series has been synthesized: (E)-3-(3-(anthracene-9-yl)acryloyl)coumarin (compound 1), 4-hydroxy-3-(5-(4-methoxyphenyl)-1-(p-tolyl)-4,5-dihydro-1H-pyrazol-3-yl)coumarin (compound 2), 3-(1-acetyl-5-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-3-yl)-4-hydroxycoumarin (compound 3), ethyl 7-(diethylamino)Coumarin-3-carboxylate (compound 4) as well as the well-known laser dye Coumarin 6 (3-(benzo[d]thiazole-2-yl)-7-(diethylamino)coumarin) used as a reference compound. The LEDs were produced by vacuum thermal spraying and spin-coating. The fluorescence and electroluminescence spectra were studied using an Ocean Optics Maya 200 PRO spectrometer. A photomultiplier was used to obtain the luminescence decay curves, PicoQuant PMA-C 192-N-M. Spectral data (absorption, photoluminescence) as well as time-resolved measurements (fluorescence attenuation time) indicate the key role of donor-acceptor interactions as well as spatial effects in the formation of electronic transitions. The current-voltage characteristics confirmed the presence of conduction modes limited by spatial charge and conduction limited by carrier capture processes. The study of the voltage-brightness characteristics showed that compound 2 demonstrates brightness comparable to the reference compound Coumarin 6, which makes it the most promising for further optimization of organic light-emitting diodes. In addition, it is shown that compound 4 in the device provides white emission with chromaticity coordinates close to daylight, which makes it potentially possible for practical use in lighting systems. The data obtained confirm the influence of donor-acceptor interactions on the properties of coumarins. The degree of conjugation of donor and acceptor fragments is directly determined by spectral shifts in the absorption and fluorescence spectra. The high brightness of compound 2-based diodes, comparable to the Cou standard, is due to its efficient donor-acceptor system which optimizes intramolecular charge transfer and increases the likelihood of radiative transitions (long lifetime of the excited state 3.5 ns). On the contrary, the acetyl group in compound 3 disrupts conjugation, leading to low brightness and short fluorescence lifetime (1.7 ns) due to nonradiative relaxation. The ability of compound 4 to provide white radiation in diodes (correlated color temperature 6410 K, close to daylight) is related to the contribution of the electron transport layer to the emission spectrum.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотолюминесценция</kwd><kwd>электролюминесценция</kwd><kwd>органические светоизлучающие диоды</kwd><kwd>кумариновые красители</kwd><kwd>взаимосвязь структура-свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photoluminescence</kwd><kwd>electroluminescence</kwd><kwd>organic light emitting diodes</kwd><kwd>coumarin dyes</kwd><kwd>structure-properties relationship</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Song J., Guan Y., Wang C., Li W., Bao X., Niu L.
