Установлено, что динамика нестационарных спектров поглощения гибридной системы (Ag–CuPc)6 Ag отражает существующее взаимное влияние плазмонной и органической подсистем на характеристики электронных состояний и спектрально-кинетические свойства друг друга. Время релаксации основной компоненты в кинетике релаксации наведенного поглощения на длине волны λ = 525 нм (τ ~ 15 пс), обусловленной синглет-триплетной релаксацией, для органической подсистемы CuPc суммарной толщиной l ~ 40 нм в гибридной структуре заметно короче времени релаксации (τ ~ 50 пс) аналогичной компоненты для чистой пленки фталоцианина меди такой же толщины. Предполагается, что присутствие наночастиц серебра в гибридной структуре (Ag–CuPc)6 Ag влияет на вероятность интеркомбинационных переходов в органической подсистеме, ускоряя переход молекул CuPc в долгоживущее триплетное состояние.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we studied the dynamics of transient absorption spectra of a hybrid nanostructure (Ag–CuPc)6 Ag based on island silver films and copper phthalocyanine thin films, as well as individual structural units of this system, by femtosecond transient absorption spectroscopy. It is found that the effects observed for a hybrid nanostructure reflect the existing mutual influence of the plasmonic and organic subsystems on the spectral-kinetic characteristics of each other. The characteristic time of the main component of induced optical density kinetics at a wavelength λ = 525 nm (τ ~ 15 ps) that is caused by singlet-triplet relaxation of the excited electronic states of the organic subsystem of the hybrid structure is noticeably shorter than the relaxation time (τ ~ 50 ps) at the same wavelength for a pure copper phthalocyanine film of 40 nm thickness, just the same as the total thickness of the organic subsystem in the hybrid structure. It is assumed that the presence of silver nanoparticles in the hybrid structure (Ag–CuPc)6 Ag, affects the probability of intersystem conversion in the organic subsystem, accelerating the transition of CuPc molecules to a long-lived triplet state due to a strong local field near the surface of the plasmon particle. The triplet-triplet absorption spectrum of copper phthalocyanine in the spectral range 470–750 nm was obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностный плазмонный резонанс</kwd><kwd>гибридные наноструктуры</kwd><kwd>фемтосекундная спектроскопия</kwd><kwd>нестационарные спектры поглощения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surface plasmon resonance</kwd><kwd>hybrid nanostructures</kwd><kwd>femtosecond spectroscopy</kwd><kwd>transient absorption spectra</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">Leznoff, C.
