Conjugated polymers are widely studied for application areas ranging from energy technology to wearable electronics and bioelectronics. To develop a truly sustainable technology, environmentally benign synthesis is essential. Here, the open-flask synthesis of a multitude of conjugated polymers at room temperature by ambient direct arylation polymerization (ADAP) is demonstrated. The batch synthesis of over 100 grams of polymer in a green solvent and continuous droplet flow synthesis without any solid support is described. Polymers prepared by ADAP are characterized by improved structural order compared to materials prepared by other methods. Hence, organic electrochemical transistors (OECTs) feature beyond state-of-the-art electrical properties, i.e., an OECT hole mobility μ as high as 6 cm V s, a volumetric capacitance over 200 F cm, and thus a figure of merit [μ] exceeding 1100 F cm V s. Thus, ADAP paves the way for the benign and large-scale production of high-performance conjugated polymers.
共轭聚合物在从能源技术到可穿戴电子设备和生物电子学等广泛的应用领域中得到了深入研究。为了开发真正可持续的技术，环境友好型合成至关重要。在此，展示了通过环境直接芳基化聚合（ADAP）在室温下于敞口烧瓶中合成多种共轭聚合物。描述了在绿色溶剂中批量合成超过100克聚合物以及在无任何固体载体的情况下进行连续液滴流合成。与通过其他方法制备的材料相比，通过ADAP制备的聚合物具有改善的结构有序性。因此，有机电化学晶体管（OECT）具有超越现有技术的电学性能，即OECT空穴迁移率μ高达6 cm² V⁻¹ s⁻¹，体积电容超过200 F cm⁻³，因此品质因数[μ]超过1100 F cm⁻³ V⁻¹ s⁻¹。因此，ADAP为高性能共轭聚合物的良性大规模生产铺平了道路。
