Highly Stable Eu(III) and Tb(III) Complexes Based on Triarylborane‐Functionalized Cyclen Derivatives as Visual Temperature Probes and White‐Light Emitters
Bibliographic record
Abstract
New and highly stable Eu(III) and Tb(III) complexes based on two triarylborane functionalized cyclen derivative ligands L1 and L2, have been achieved. The Eu(III) and Tb(III) lanthanide compounds have been found to display highly distinct and contrasting temperature‐dependent dual emission and decay lifetimes, rendering them as potential sensitive temperature probes. The emission colors of the new lanthanide complexes can be tuned by controlling the ratio of the Eu(III) and Tb(III) complexes in a binary composite and the temperature. Bright white light emission based on the new binary Eu(III) and Tb(III) complexes has been achieved. Furthermore, the triarylborane functionality of the new complexes enables their use as effective probes for anions such as fluoride ions, allowing the further tuning of the lanthanide emission.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
