Abstract
Abstract Recently, hydrogen‐bonded organic frameworks (HOFs) have emerged as a rapidly advancing class of porous materials with significant potential for applications in the absorption and detection of various chemicals. Here, the unique ability of amide groups to form endless‐stacking H‐bonds is implemented in the design of HOFs. Starting from benzene‐1,3,5‐tricarboxamide and amide‐containing tribenzocyclynes as foundational building blocks, a diverse range of HOFs featuring 1D, 2D, or 3D hydrogen‐bonded frameworks has been synthesized. Among those, all three porous HOFs, HOF_B‐Hex, HOF_T‐Pr and HOF_T‐Hex exhibited permanent porosity, thereby demonstrating the effectiveness of amide‐based HOFs strategy. Notably, HOF_T‐Hex stands out with a 42% pore volume and an impressive iodine capture efficiency of 6.4 g g −1 . The iodine capture capacity is influenced not only by pore volume but also by the presence of accessible π‐electrons within the material (i.e., electrons not engaged in a π–π stacking interaction. Furthermore, some of these HOFs exhibited fluorescent responses to iodine positioning them as highly promising materials for both the capture and sensing of iodine.

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
