Abstract
Periodic mesoporous organosilicas with two-dimensional and three-dimensional hexagonal as well as cubic ( Pm 3 n ) symmetry were synthesized using bridged silsesquioxane species (RO) 3 Si−CH 2 −CH 2 −Si(RO) 3 as precursors and cetyl- or octadecyltrimethylammonium chloride (C 16 TMACl or C 18 TMACl) as structure-directing species. These materials were characterized by N 2 adsorption, SEM, TEM, and solid-state MAS NMR spectroscopy. 13 C and 29 Si NMR data showed unambiguously that all carbon atoms were covalently linked to Si. The cubic material obtained in the presence of C 16 TMACl and 1,2-bis(trimethoxysilyl)ethane (BTME) first formed into truncated rhombic dodecahedral particles that grew into spheres. The sample prepared in the presence of C 18 TMACl and BTME at 100 °C was entirely comprised of concentrically self-assembled 10-μm hexagonal rods. Using C 16 TMACl in the presence of 1,2-bis(triethoxysilyl)ethane (BTEE) at 95 °C afforded high-quality two-dimensional hexagonal organosilica comprised of unusually long (30−40 μm) faceted empty tubules.

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 it
