Abstract
Polymeric allotropes of nitrogen and nitrogen‐rich compounds containing NN single bonds are attractive candidates for high‐energy‐density materials. However, the low kinetic stability of single bond in nitrogen means that these materials have to be synthesized under high pressure and temperature. Recent advances of experimental high‐pressure techniques and computational structure prediction methods have enabled the investigation of many new nitrogen phases and nitrogen‐rich compounds, and some have been successfully synthesized. Some of the recently synthesized materials have been retrieved at ambient conditions, and the large hysteresis warrants further application‐inspired research. This review introduces the important classes of nitrogen‐rich materials ranging from fundamental insight into bonding in nitrogen, to theoretical investigation of hypothetical compounds, and to laboratory realization of these energetic materials in diamond anvil cell. The progressive development of the field is narrated in chronological order, with the emphasis placed on recent progress in the last 2 years.

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 it
