Lanthanide complexes with (4,7-dichloro-1,10-phenanthroline-2,9-diyl)bis(pyrrolidin-1-ylmethanone): bifunctional materials for homogeneous catalysis and luminescent thermometry

The first bifunctional materials for simultaneous catalysis and temperature measurements were obtained based on europium and ytterbium complexes with (4,7-dichloro-1,10- phenanthroline-2,9-diyl)bis(pyrrolidin-1-ylmethanone). The complexes demonstrated intense visible and NIR luminescence, the ability to homogeneously catalyze the Henry reaction, and high luminescence sensitivity to temperature (S_r = 1.7% K⁻¹).
