Abstract:碳-碳偶联是合成多孔有机聚合物的基本设计原理,在气体吸附/分离、光催化、储能等领域有着广泛的应用。然而,由于C(sp3) -C (sp3)偶联反应的低活性和未知的副反应是阻碍该领域聚合发展的一大障碍。本文报道了催化剂Ni(COD)2在温和的反应条件下实现了高效的C(sp3) -C (sp3)均相偶联反应,构建了多孔线性结晶聚合物和柔性三维多孔芳香框架(paf)。由二溴甲基芳烃生成的线性聚合物由于反应位点可控性,结晶度好,熔点高(Tm = 286℃)的优势。此外,由三/四溴甲基芳烃衍生的DAFs(PAF-64、PAF-65和PAF-66)由于其柔性骨架,具有高表面积(SBET = 390 m2 g−1)和高甲烷储存容量(高达313 cm3 cm−3)。这项工作为通过C(sp3) -C (sp3)偶联反应构建新型多孔聚合物和开发甲烷储存材料提供了新的思路。
