High Surface Area Networks from Tetrahedral Monomers: Metal-Catalyzed Coupling, Thermal Polymerization, and Click Chemistry

A series of tetrahedrally linked conjugated microporous polymer networks were prepared using a variety of bond-forming chemistries including Sonogashira-Hagihara coupling, Yamamoto coupling, thermal alkyne condensation, and click chemistry. These thermally stable polymers exhibit high surface areas (up to 3200 m(2)/g) and adsorb up to 2.34 wt % hydrogen by mass at 1.13 bar/77 K and 7.59 wt % carbon dioxide by mass at 1.13 bar/298 K.
