π-Electron Conjugation in Two Dimensions
Abstract
Organic oligomers and polymers with extended π-conjugation are the fundamental building blocks of organic electronic devices. Novel routes are being explored to create tailor-made organic materials, and recent progress in organic chemistry and surface chemistry has led to the synthesis of planar 2D polymers. Here we show how extending π-conjugation in the second dimension leads to novel materials with HOMO-LUMO gaps smaller than in 1D polymers built from the same parent molecular repeat unit. Density functional theory calculations on experimentally realized 2D polymers grant insight into HOMO-LUMO gap contraction with increasing oligomer size and show fundamental differences between 1D and 2D "band gap engineering". We discuss how the effects of cross-conjugation and dihedral twists affect the electronic gaps.

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.
