Bent-Core and Nematic Liquid Crystal Functionalized Gold Nanorods
Bibliographic record
Abstract
Gold nanorods (GNRs) functionalized with trimethoxysilane terminated nematic or bent-core liquid crystals (LCs) are described. In the first step, cetyltrimethylammonium bromide (CTAB) surfactant-stabilized GNRs were prepared using a single step, non-seeding method. The CTAB capping on the GNRs was then replaced in a two-step process first by binding of mercaptopropyltrimethoxysilane followed by immobilization of the nematic or bent-core LC silane by a dehydration condensation. The final LC-decorated GNRs were characterized by UV-vis-NIR spectrophotometry, IR spectroscopy and transmission electron microscopy (TEM). The functionalized nanorods were found to be stable, well dispersible in non-polar organic solvents. The bent-core LC-capped GNRs exhibited only short-range self-assembly after slow evaporation of the solvent on TEM grids. However, the nematic LC-decorated rods displayed regular patterns of self-assembled GNRs on TEM grids after annealing the sample in the presence of an external magnetic field.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
