説明
<jats:p> Covalent organic frameworks (COFs) have been designed and successfully synthesized by condensation reactions of phenyl diboronic acid {C <jats:sub>6</jats:sub> H <jats:sub>4</jats:sub> [B(OH) <jats:sub>2</jats:sub> ] <jats:sub>2</jats:sub> } and hexahydroxytriphenylene [C <jats:sub>18</jats:sub> H <jats:sub>6</jats:sub> (OH) <jats:sub>6</jats:sub> ]. Powder x-ray diffraction studies of the highly crystalline products (C <jats:sub>3</jats:sub> H <jats:sub>2</jats:sub> BO) <jats:sub>6</jats:sub> ·(C <jats:sub>9</jats:sub> H <jats:sub>12</jats:sub> ) <jats:sub>1</jats:sub> (COF-1) and C <jats:sub>9</jats:sub> H <jats:sub>4</jats:sub> BO <jats:sub>2</jats:sub> (COF-5) revealed expanded porous graphitic layers that are either staggered (COF-1, <jats:italic>P</jats:italic> 6 <jats:sub>3</jats:sub> / <jats:italic>mmc</jats:italic> ) or eclipsed (COF-5, <jats:italic>P</jats:italic> 6/ <jats:italic>mmm</jats:italic> ). Their crystal structures are entirely held by strong bonds between B, C, and O atoms to form rigid porous architectures with pore sizes ranging from 7 to 27 angstroms. COF-1 and COF-5 exhibit high thermal stability (to temperatures up to 500° to 600°C), permanent porosity, and high surface areas (711 and 1590 square meters per gram, respectively). </jats:p>
