Abstract
The fabrication of porous materials possessing ultrahigh specific surface areas remains a significant challenge. We report the synthesis of two novel porous aromatic frameworks, PAF-336 and PAF-337, constructed from 6- and 8-connected building blocks with triangular prismatic and cuboid geometries, respectively. PAF-336 demonstrates an ultrahigh specific surface area (~5,210 m2·g-1) and large pore volume (3.5 cm3·g-1). This high porosity translates to high hydrogen storage capacity and state-of-the-art methane storage performance, positioning PAF-336 as a potential material for clean energy storage.
