Polymers with Bipolar Carrier Transport Abilities for Light Emitting Diodes
Abstract
Efficient and stable polymer light emitting diodes (LEDs) have recently been extensively pursued. To achieve efficient LED performance for a single layer device, a polymer with bipolar carrier transport abilities and high-luminescence quantum yields is desired. We envision that if an emissive polymer combines both electron and hole transporting segments, it could possess comparable bipolar carrier transport ability. In this paper, we report two oxadiazole-containing poly(phenylenevinylenes) (PPVs). An oxadiazole unit is introduced into the polymer backbone to improve the electron injection/transport properties. The oligo(phenylenevinylene) segments function as both hole transporter and emitter. In one polymer, carbazole is introduced in the side chain to improve the hole tranport properties. The syntheses and device evaluations of these polymers are reported.

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.
