“…The second adsorption bands at 1400-1650 cm -1 corresponded to skeletal vibration of benzene ring. The third peak at 2200-2350 cm -1 corresponded to -C:C-vibration stretching and the fourth peak near 2900 cm -1 was assigned to the -Ar-H stretching [28,30]. FTIR spectra demonstrated that BCMP-1 and BCMP-2 mainly consisted of aromatic rings and C:C bonds, in accordance with the 13 C NMR analysis and Fig.…”

“…In our previous studies, a variety of CMPs with different morphologies and functionalities have been designed and synthesized as porous mediums for various purposes including hydrogen storage [23,24], CO 2 capture [25][26][27], iodine capture [27], composites [28], and oil absorption [22,[29][30][31]. In particular, we firstly reported the superhydrophobic and superoleophilic wettabilities of the CMPs [22].…”

Two novel CMPs networks with (A 4 ? B 3 ) type and (A 4 ? B 2 ) 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 2 g -1 .Using them as porous platforms, the CO 2 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.

“…films, membranes, foams, aerogels...). A large variety of microporous polymers such as hypercrosslinked polymers (HCPs), conjugated microporous polymers (CMPs), porous aromatic frameworks (PAFs) or polymers of intrinsic microporosity (PIMs) have attracted a growing technological interest for applications in gas storage [3,4], catalysis [5,6], and separations [7][8][9].…”

“…The microscopic study showed that MPP had an intriguing microstructure consisting of tubular polymers. There have been a few reports on tubular or fibrillar cross‐linked polymers, but the mechanisms for their formation have not been fully understood. We previously reported that the Sonogashira–Hagihara coupling reaction of 1,3,5‐triethynylbenzene with the bis(bromothiophene) monomer produced a compressible monolith consisting of tubular polymer fibers .…”

A flexible microporous polymer paper (MPP) is prepared with the polymer tubes obtained from the Sonogashira coupling reaction of 1,4‐diiodotetrafluorobenzene and 1,3,5‐triethynylbenzene. MPP has an interconnected network structure of polymer tubes and shows a hierarchical pore structure. Relatively large pores are formed among entangled polymer tubes, while micro‐ and mesopores are generated in the tube walls. MPP is foldable, mechanically stable, and stretchable. When the folding stress is removed, a wrinkle forms along the folded line, as observed in common papers composed of cellulose pulps. The mechanical stability of MPP results from electrostatic interactions between electron deficient tetrafluorobenzene units and electron rich triethynylbenzene units in the polymer. The tensile stress–tensile strain curve shows that MPP can elongate up to 15% strain. MPP is superhydrophobic, showing a water contact angle of 162° and can be used for the filtration of small molecules such as a dye and iodine.
