Synthesis of robust MOFs@COFs porous hybrid materials via aza Diels Alder reaction: towards high performance supercapacitor materials.
Metal organic frameworks (MOFs) and covalent organic frameworks (COFs) attracted enormous attention in recent years. Recently, MOF@COF are emerging as hybrid architectures combining the unique features of the individual components to enable the generation of materials displaying novel physicochemical properties. Herein we report an unprecedented use of aza Diels Alder cycloaddition reaction as postsynthetic modification of MOF@COF LZU1, to generate aza MOFs@COFs hybrid porous materials with extended p delocalization. A a proof of concept, the obtained aza MOFs@COFs is used as electrode in supercapacitors displaying specific capacitance of 20.35 uF cm 2 and high volumetric energy density of 1.16 F cm 3 Our approach of postsynthetic modification of MOFs@COFs hybrids implement rational design for the synthesis of functional porous materials and expands the plethora of promising application of MOFs@COFs hybrid porous materials in energy storage applications.
