N-heteroacenes as an organic gain medium for room temperature masers
Bibliographic record
Abstract
The development of future quantum devices such as the maser, i.e., the microwave analog the laser, could be well-served by exploration of chemically tuneable organic materials. Current iterations of room temperature organic solid-state masers are composed of an inert host material that is doped with a spin-active molecule. In this work, we have systematically modulated the structure of three nitrogen-substituted tetracene derivatives to augment their photoexcited spin dynamics and then evaluated their potential as novel maser gain media. To facilitate these investigations, we adopted an organic glass former, 1,3,5-tri(1-naphthyl)benzene (1-TNB) to act a universal host. These chemical modifications impacted the rates of intersystem crossing, triplet spin polarisation, triplet decay and spin-lattice relaxation, leading to significant consequences on the conditions required to surpass the maser threshold.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
