- Abstract
Two novel CMPs networks with (A + B) type and (A + B) type were synthesized by Pb(II)/Cu(I)-catalyzed Sonogashira-Hagihara cross-coupling polymerization. The resulting CMPs show high thermal stability with a decomposition temperature above 300 °C. The CMPs exhibit high specific surface areas up to 788 m g. Using them as porous platforms, the CO adsorption of CMPs was investigated. Meanwhile, the synthesized CMPs show surface superhydrophobicity with water contact angle about 157° due to the microporous morphological structures and the strongly hydrophobic chemical compositions. The organic liquid uptake of CMPs samples was measured up to 1522 wt% for a variety of organic solvents. Furthermore, simply coating of the resulting CMPs on the stainless steel grid enables the wettability of grid changing from hydrophilicity to superhydrophobicity and superoleophilicity, which makes them potential candidates for selective adsorption of oils and organics from water.
