摘要
The unique structure and properties make graphene very promise for a wide range of potential applications, including energy storage and conversion, electronics, sensors, and electrocatalysis[1-3]. Similar to grapheme, we developed series of covalent organic polymers(COPs), which were constructed from covent bonds(C-C coupling) between the ever-changing organic linkers by homo- or hetero-polymerization[4, 5]. Moreover, we have developed a class of covalent organic polymers(COPs) incorporating a metal(such as Fe, Co, Mn) with precisely controlled locations of nitrogen heteroatoms and holes were synthesized from various N-containing metal–organic complexes[2, 6]. Owing to their high porosity, precisely-controlled molecular structures and multi-functionalities, COPs hold great potential for efficient energy conversion and storage, particularly as efficient metal-free electrocatalysts for oxygen reduction reaction(ORR) in fuel cells[1, 5, 7]. As to the energy storage, the synthesized N-CPAF-1 possesses large capacitance(385 F/g) and excellent performance stability without any loss in capacitance after 9000 charge–dischargecycles[8].
