Реферат: Lanthanide complexes are widely used in both luminescent thermometry and catalysis, yet their integration into a single material remains a major challenge. Herein, we report novel terbium and europium complexes with a bispidine-based ligand conjugated to benzoic acid via a triazole linker. These complexes exhibit dual functionality: they act as homogeneous catalysts for the Michael addition reaction and simultaneously serve as ratiometric luminescent thermometers. The mixed-metal complex (Eu0.1Tb0.9)(L)(TFA)2·H2O demonstrates bright emission with quantum yields up to 56 %, and europium lifetime-based thermometry shows a relative sensitivity of 1.7 %/ °C with a temperature uncertainty below 0.5 °C. Notably, the catalytic activity arises only in the metal-ligand complex form, as neither the ligand nor lanthanide salts alone promote the reaction. To the best of our knowledge, this is the first report of a rare-earth complex combining homogeneous catalysis with luminescent thermometry in solution.
