Platinum‐Centered Oligoynes Capped by Boron Difluoride Formazanate Dyes and Their Thin‐Film Properties
Bibliographic record
Abstract
Abstract Since the Nobel prize winning discovery that polyacetylene could act as a semiconductor, there has been tremendous efforts dedicated to understanding and harnessing the unusual properties of π‐conjugated polymers. Much of this research has focused on the preparation of oligoynes and polyynes with well‐defined numbers of repeating alkyne units as models for carbyne. These studies are usually hampered by a structure‐property relationship where the stability of the resulting materials decrease with the incorporation of additional alkyne units. Here, we describe a series of oligoynes, with up to 12 alkyne units, where electron‐rich [Pt(PBu 3 ) 2 ] 2+ units are incorporated at the center of the oligoyne backbones which are capped by electron‐poor BF 2 formazanate dyes. These compounds exhibit excellent stability and solubility, panchromatic absorption, and redox activity characteristic of their structural components. These traits facilitated thin‐film studies of extended oligoyne materials, where it is shown that incorporating [Pt(PBu 3 ) 2 ] 2+ units leads to smoother films, decreased conductivity on the microscale, and increased conductivity on the nanoscale when compared to metal‐free analogs. Remarkably, our oligoynes have superior conductivity compared to the ubiquitous poly(3‐hexylthiophene) semiconductor.

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.
