“…Eu(III) carboxylate dibenzoylmethanates (CDMs) have unique optical and magnetic properties [12,13]. In continuation of our studies [12][13][14][15][16][17] on investigation of the optical chemosensor properties of Eu(III) complexes, in the present work we report the results of an investigation of the luminescent chemosensor properties of Eu(III) CDMs of the composition Eu(Dbm) 2 Acid • nH 2 О, where Dbm is the dibenzoylmethanate ion; Acid is the anion of a carboxylic acid, namely, formic (Form − ), acetic (Ас − ), propionic…”
Luminescent chemosensor properties of Eu(III) carboxylate dibenzoylmethanates are observed. It is shown that the interaction of Eu(III) complexes with ammonia or methylamine vapors leads to an increase in the Eu(III) luminescence intensity. An optical response mechanism related to the interaction between the analyte and Eu(III) complex molecules and to suppression of luminescence quenching is proposed.

“…For the crystal structure of a multinuclear analogue of the title compound, see [9]. Analogous mononuclear coordination compounds have also been reported for praseodymium [10], neodymium [11], samarium [10], europium [12,13], holmium [14] and erbium [10]. In the crystal, three possible hydrogen bonds supported by the coordinated water molecule as donor and lanthanum-coordinated oxygen atoms as acceptors are identified.…”
“…Карбоксилатодибензоилметанаты (КДМ) Eu(III) обладают уникальными оптическими и магнитными свойствами [12,13]. В продолжение наших работ [12][13][14][15][16][17] ной группы комплексов практически постоянна и составляет 200−225 cm −1 . Следует отметить, что соединения второй группы обладают значительной люминесценцией и при 300 K в отличие от соединений первой группы, для которых характерно практически полное тушение люминесценции при комнатной температуре [12].…”
Обнаружены люминесцентные хемосенсорные свойства карбоксилатодибензоилметанатов Eu(III). Показано, что взаимодействие комплексов Eu(III) с парами аммиака или метиламина приводит к увеличению интенсивности люминесценции Eu(III). Предложен механизм оптического отклика, связанный с взаимодействием между молекулами аналита и комплекса Eu(III) и блокированием процесса тушения люминесценции. Ключевые слова: европий(III), карбоксилатодибензоилметанаты, люминесценция, хемосенсоры, аммиак, метиламин.
