Phase Behaviors and Photoresponsive Thin Films of Syndiotactic Side‐Chain Liquid Crystalline Polymers with High Densely Substituted Azobenzene Mesogens
Bibliographic record
Abstract
Abstract Azobenzene‐containing polymers (azopolymers) are a kind of fascinating stimuli‐responsive materials with broad and versatile applications. In this work, a series of syndiotactic C1 type azopolymers of P m ‐Azo‐C n with side‐chain azobenzene mesogens of varied length alkoxy tails ( n =1, 4, 8, 10) and different length alkyl spacers ( m =6, 10) have been prepared via Rh‐catalyzed carbene polymerization. The thermal properties and ordered assembly structures of thus synthesized side chain liquid crystalline polymers (SCLCPs) have been systematically investigated with differential scanning calorimetry (DSC), polarized optical microscopy (POM) and variable‐temperature small/wide‐angle X‐ray scattering (SAXS/WAXS) analyses. P10‐Azo‐C1 and P10‐Azo‐C4 with shorter alkoxy tails exhibited hierarchical structures SmB/Col ob and transformed into SmA/Col ob at a higher temperature, while P10‐Azo‐C8 and P10‐Azo‐C10 with longer alkoxy tails only displayed side group dominated layered SmB phase and transformed into SmA phase at higher temperatures. For P6‐Azo‐C4 with a shorter spacer only showed a less ordered SmA phase owing to interference by partly coupling between the side chain azobenzene mesogens and the helical backbone. More importantly, the series high densely substituted syndiotactic C1 azopolymer thin films, exhibited evidently and smoothly reversible photoresponsive properties, which demonstrated promising photoresponsive device applications.

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.
