摘要
A new fluorescent amine probe of complex Eu(TTolB) 3 (Phen) ( 1 ) (Phen = 1,10-phenanthroline, TTolB = 4-Trifluoro-1-(4-methylphenyl)−1,3-butanediketonate) is designed and synthesized. Single-crystal X-ray diffraction shows that 1 •hexane crystallizes into solvated mononuclear ternary molecules. This material exhibits strong red emission dominated by the Eu 3+ ( 5 D 0 → 7 F 2 ) transition not only in solid but also in doped film. Based on this probe, a thin film fluorescence sensor with highly sensitive and selective response to aniline and methylamine was developed by PMMA composite and cellulose-paper support. When the sensor was exposed to aniline/methylamine vapor, its photoluminescence (PL) emission showed a sensing behavior of rapid quenching. • A new fluorescent amine probe of a ternary europium(III) complex material. • Strong red characteristic emission of Eu 3+ in solution, doped film or solid state. • Thin film fluorescence sensor developed by PMMA composite and cellulose paper support. • PL emission of the sensor showed a sensing behavior of rapid quenching. • Highly sensitive and selective response to aniline and methylamine.
