Red-emissive poly(phenylene vinylene)-derivated semiconductors with well-balanced ambipolar electrical transporting properties

Author affiliations

Abstract

Herein, two new poly(phenylene vinylene)-derivated semiconductors, poly(benzopyrrolone-p-phenylene-vinylene) (PBPPV) and poly(benzopyrrolone-di-p-phenylene-vinylene) (diPBPPV), are designed and synthesized with lactam groups as the electron-deficient and lateral extending units and phenylethylene as the emissive element for achieving integrated optoelectronic properties. Comprehensive characterization demonstrates that both PBPPV and diPBPPV are red-emissive materials with a photoluminescent quantum yield (PLQY) of up to 7% and exhibit well-balanced ambipolar transport properties with the electron and hole mobility approaching 4.5 × 10−4 cm2 V−1 s−1 and 3.0 × 10−4 cm2 V−1 s−1, respectively. This work provides valuable guidelines for further improvement of integrated optoelectronic conjugated polymers by rational molecular design.
