Generic way for functionalised well-ordered cubic mesoporous silica via direct synthesis approach
Bibliographic record
Abstract
Applications of functionalised mesoporous silica are dependent upon the location, the quantity and the accessibility of the functional groups attached in the inner pores, particularly in the case of cubic ordered porous structure. Facilitating such material synthesis could be of great interest. Herein, we present a controlled and generic route to functionalised and well-ordered cubic mesoporous silica by direct synthesis and an efficient method for complete template removal without structure collapse nor loss of organic content, leading to better functional accessibility and thus material capability. Materials were obtained by co-condensation of tetraethylorthosilicate (TEOS) and an organotriethoxysilane Σ-(CH2)3-Si(OR′)3 (with R′ = Me or Et and Σ = CN, SH, CH3COCHCOCH3 (acac) and PO(OEt)2) in the presence of F127 as structure-directing agent in acidic media. All materials were characterised by XRD, TEM, TGA, 13C and 29Si NMR spectroscopies, nitrogen gas adsorption–desorption measurements as well as elemental analyses. Functional accessibility and adsorption capacity of such materials were proved by complexation of lanthanide ions thanks to acac groups.

How this classification was reachedexpand
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.
