New Insights into the Microstructure of GILCH-Polymerized PPVs
Abstract
The microstructure of GILCH-polymerized PPVs was examined by NMR techniques. Selectively main-chain 13 C-labeled polymers were prepared and investigated by 1 H NMR, 13 C NMR, and 2D NMR methods. Only one major polymerization defect was discovered: tolane−bisbenzyl (TBB) moieties could be proven in amounts of 1.5−2.2% for OC 1 C 10 −PPV. Furthermore, indications for ether-type end groups (∼0.2%) were found. These defects are readily explained by the polymerization mechanism. Other structural elements (e.g., cis double bonds, branching) were not detected.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
