Abstract
Tetra(4-dihydroxyborylphenyl)germanium as the tetrahedral units and 1,2,4,5-tetrahydroxybenzene as linkers were selected to form a crystalline porous aromatic framework, CPAF-13, with the planar five-membered BO2C2 ring in its structure by a dehydration reaction. The crystallinity of CPAF-13 was confirmed by x-ray diffraction analysis. The Ar sorption measurement on activated CPAF-13 results in a surface area of 417 m2/g, using Brunauer Emmett Teller model. CPAF-13 also shows a considerable adsorption capacity of H2.
