Lanthanide macrocyclic quinolyl conjugates as luminescent molecular switches and integrated logic gates using H+ and O2 as inputs
Bibliographic record
Abstract
The design and synthesis of 1Tb, a Tb(III) quinoline?cyclen based complex, are described. The results from the photophysical investigation of 1Tb are compared with the results observed from its Eu(III) analogue, 1Eu. The Tb(III) emission of 1Tb was found to be highly pH dependent, being reversibly switched off?on?off, with maximum emission intensities observed within the physiological pH range, contrary to what was observed with the Eu(III) analogue. Furthermore, the Tb(III) emission was also found to be sensitive to molecular oxygen concentration. By using a stoichiometric amount of both complexes, the changes observed in the combined lanthanide Eu/Tb-emissions (described as output) as a function of pH and O2 (as ion/molecular inputs) can be employed in ratiometric sensing of these analytes. Furthermore, the outputs can also be described in molecular logic gate terms, where the emission at three different emission wavelengths can be described in terms of Boolean algebra, corresponding to the NAND, NOR and NOT logic gates functions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
