TLDR: In this article, a direct synthesis methodology is proposed as a guidance for the bulk synthesis of organic framework materials for energy electrocatalysis, and a free-standing POF film, hybrid of POF and nanocarbon, and cobalt-coordinated POF is presented.

Abstract: Organic framework materials constructed by covalently linking organic building blocks into framework structures are highly regarded as paragons to precisely control the material structure at the atomic level. Herein, a direct synthesis methodology is proposed as a guidance for the bulk synthesis of organic framework materials. Framework porphyrin (POF) materials are one-pot synthesized to demonstrate the advances of the direct synthesis methodology. The as-synthesized POF materials are intrinsically 2D and exhibit impressive versatility in composition, structure, morphology, and function, delivering a free-standing POF film, hybrids of POF and nanocarbon, and cobalt-coordinated POF. When applied as electrocatalysts for oxygen reduction reaction and oxygen evolution reaction, the cobaltcoordinated POF exhibits excellent bifunctional electrocatalytic performances comparable with noble-metal-based electrocatalysts. The direct synthesis methodology and resultant POF materials demonstrate the ability of controlling materials at the atomic level for energy electrocatalysis.
