Photoinduced electron transfer in multilayer films composed of conjugated polyelectrolyte and amphiphilic copolymer hosting electron acceptor molecules
Bibliographic record
Abstract
Ultrathin multilayer films composed of conjugated anionic polyelectrolyte, poly(8-(3-thienyl)octanosulfonate) (P3TOSNa), and positively charged poly(N,N-dimethyl-N-4′-vinylbenzyl-N-2-(decanoyl-N′-methylimino)ethylammonium chloride)-co-(N,N,N-trimethyl-N-4′-vinylbenzylammonium chloride) (Ak-St-H) have been fabricated using the layer-by-layer technique. UV-Vis spectroscopy, atomic force microscopy and spectroscopic ellipsometry were applied for thickness and morphology characterization revealing regular growth and smooth surfaces of the films. An electron accepting molecule (butyl viologen) was then successfully entrapped inside the hydrophobic domains formed by Ak-St-Hvia a solubilization procedure. Photoinduced electron transfer from P3TOSNa polymer to butyl viologen molecules has been observed inside the nanostructured multilayers as confirmed by steady-state fluorescence spectroscopy and time-resolved fluorescence decay measurements. The structure of this water-born film helps to protect the hydrophobic acceptor molecules from aggregation and enables efficient charge separation within the film that is one of the crucial steps in organic photovoltaic systems.

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.
