Dinuclear Europium Complexes: Thermometric Response Tuned by Ligands

Two dinuclear EuIII complexes, [Eu2(bpm)(dbm)6] and [Eu2(bpm)(btfa)6], demonstrate how terminal ligands modulate luminescent thermometry. The complexes operate in distinct temperature ranges, 270-420 K and 300-440 K, with maximum relative sensitivities of 3.4% K–1 and 3.6% K–1. Ariane C. F. Beltrame published this dataset on figshare in April 2026.

Use Cases

• Analyzing the relationship between ligand structure and luminescent thermometric performance based on described complexes.
• Comparing nonradiative decay rates and activation energies for thermal quenching based on C–H bond count and structural packing.
• Investigating the impact of terminal ligands on S1 and T1 state energies and intermolecular energy transfer processes.
• Evaluating crystal system and coordination geometry differences induced by β-diketone ligands.
• Using the 5D0 excited-level lifetime as a thermometric parameter to model temperature sensitivity.

Strengths

• Dataset includes crystallographic information file (CIF) format data, likely containing structural coordinates.
• Specific temperature operating ranges and maximum sensitivities are provided for each complex.
• The study compares two distinct ligand systems (dbm– and btfa–) enabling controlled analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect methodological bias inherent to the specific synthetic and analytical approach.
