weight. The resultant Py-HBPIL(Br)@rGO hybrid material displayed much better catalytic activity than ever reported immobilized IL catalysts for coupling reaction between CO2 and propylene oxide (PO), and it has been reused up to 6 times by simple filtration process without significant decline in activity. Furthermore, the combination of bifunctional HBP and π-π stacking immobilization may provide a general
                                    通过简便的三步法合成了在主链中具有高密度
离子液体(IL)部分和链端可控control基量的双功能超支化聚合物(HBP)的第一个例子,然后通过π-π堆积相互作用将其固定在还原的氧化
石墨烯(rGO)上。在链端的10%处带有pyr基的Py-HB
PIL(Br)可以实现73%重量的最高固定负载。所得的Py-HB
PIL(Br)@rGO杂化材料显示出比以往报道的固定化IL催化剂更好的催化活性,可用于
CO2与环氧
丙烷(PO)之间的偶联反应,并且通过简单的过滤工艺已重复使用了6次,而没有明显的影响活动下降。此外,
