Abstract

fetched live from OpenAlex

The templated growth of 1D assemblies of perylene diimides (PDI) formed within a conjugated polymer is described. The formation of this unique morphology is accomplished through the synthesis of a PDI-functionalized conjugated polymer and its solution casting in the presence of PDI. The strategy is demonstrated with poly(3-hexylthiophene) (P3HT), partially functionalized at the 4-position with N -(1-hexylheptyl)- N ′-(12-carboxylicdodecyl)perylene-3,4,9,10-tetracarboxylbisimide (PP3HT). The 1D assemblies of PDI embedded in the optoelectronically active polymer are hundreds of nanometers wide, 10−20 nm thick, several micrometers in length, and run parallel to the surface of the substrate. Surrounding the 1D structures is a heterogeneous PP3HT-PDI blend, comprising PP3HT domains less than 10 nm in size. Excitation energy in thin film blends of PP3HT:PDI is quenched to a much greater extent than simple molecular blends of P3HT and PDI. These systems represent structures of multiple hierarchy, wherein nanosized domains of a π-conjugated polymer and an n-type material are in intimate contact and which encapsulate 1D assemblies of nanocrystallites that run parallel to the films surface. They offer an alternative route for the fabrication of innovative supramolecular structures for optoelectronic applications.

Not 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.
