Flow chemistry has been shown to be an excellent tool for the production of conjugated polymers. In some cases, however, this technique reaches its limits because of viscosity increases or precipitate formation. Droplet flow can provide an answer but has not been developed yet for the state-of-the-art push–pull conjugated polymers applied in many prototype organic electronic devices. In this work, a droplet flow protocol is established for a near-infrared photoactive [1,2,5]thiadiazolo[3,4-g]quinoxaline-based alternating copolymer, representing the first implementation of flow synthesis for organic photodetector materials. High-quality polymers are obtained with an enhanced consistency in molar mass, dispersity, and photodetector performance.

朝着有机光电探测器大规模实施的近红外响应推挽共聚物的连续液滴流合成

流动化学已被证明是生产共轭聚合物的出色工具。但是，在某些情况下，由于粘度增加或形成沉淀，该技术达到了极限。液滴流可以提供答案，但尚未开发用于许多原型有机电子设备中的最新推挽共轭聚合物。在这项工作中，为近红外光敏[1,2,5]噻二唑并[3,4- g ]喹喔啉类交替共聚物建立了液滴流动方案，代表了有机光电探测器材料流动合成的第一个实施方案。获得具有摩尔质量，分散性和光电检测器性能增强的一致性的高质量聚合物。
