Electrochemical oxygen reduction reaction (ORR) is a very important reaction for green and sustainable chemistry. Herein, we report the design and synthesis of a semi-crystalline metallopolymer consisting of ferric porphyrin–based building blocks immobilized by organic linkers (viz. various dialdehydes) through rigid imine bonds. All the materials thus obtained showed moderate to high ORR performance in rotating ring-disk electrode voltammetry with oxygen-saturated 0.5 M H₂SO₄ and 0.1 M KOH.

卟啉铁基聚合物可减少电化学氧

电化学氧还原反应（ORR）对于绿色和可持续化学而言是非常重要的反应。本文中，我们报道了一种半结晶金属聚合物的设计与合成，该半结晶金属聚合物由卟啉铁基结构单元组成，这些结构单元通过刚性亚胺键固定在有机连接基（即各种二醛）上。这样得到的所有材料在用氧饱和的0.5MH ₂ SO ₄和0.1M KOH的旋转环盘电极伏安法中显示出中等到高的ORR性能。
