Полученное соединение идентифицировано методами1H ЯМР,13C ЯМР, масс-спектрометрии и оптической спектроскопии в УФ и видимом диапазонах. При добавлении Cd 2+ наблюдалось тушение флуоресценции. Оптимизированы условия протекания реакции, включая селективность, количество Cd 2+ , время реакции и температуру. В сравнении с ионами других металлов, таких как Li+ , Na+ , K+ , Pb2+ , Ni2+ , Zn2+ , Mn2+ , Hg2+ , Cr3+ , Cu2+  и Fe3+ , присутствие в исследуемом продукте ионов Cd 2+ вызывало высокоселективное изменение флуоресценции. При оптимальных условиях наблюдалась линейная зависимость между интенсивностью флуоресценции и концентрацией Cd 2+ в области 0-7.226×10- 5  М. Предел обнаружения 2.69 мкM. Показано, что синтезированное с использованием 2-метилиндола вещество может служить в качестве быстрого детектора ионов Cd 2+ . </p></abstract><trans-abstract xml:lang="en"><p>A novel chemosensor exhibiting highly selective recognition of Cd 2+ over other metal ions with significant fluorescence quenching was designed and synthesized by a click reaction of dialkyne and indole azide precursors. The compound was identified by1H NMR,13C NMR, MS, and UV-vis spectroscopy. The fluorescence quenching phenomenon was observed with the addition of Cd 2+ . The reaction conditions, including the selectivity, the amount of Cd 2+ , reaction time, and temperature, were optimized in the article. The product exerted highly selective fluorescence change in the presence of Cd 2+ over other metal ions, such as Li+ , Na+ , K+ , Pb2+ , Ni2+ , Zn2+ , Mn2+ , Hg2+ , Cr3+ , Cu2+ , and Fe3+ . Under the optimal conditions, a linearly proportional relationship between fluorescence intensity and the concentration of Cd2+was revealed in the range from 0 to 7.226×10- 5  M. The limit of detection was 2.69 μM. The results suggest that the substance synthesized with 2-methylindole is a novel and quick detector for Cd 2+ . </p></trans-abstract><kwd-group xml:lang="ru"><kwd>обнаружение Cd 2+</kwd><kwd>тушение флуоресценции</kwd><kwd>производное индола</kwd><kwd>флуоресцентный датчик</kwd><kwd>Cd 2+ detection</kwd><kwd>fluorescence quenching</kwd><kwd>indole derivative</kwd><kwd>fluorescence sensor</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">R.
