A series of thiophene-based conjugated microporous polymers (ThPOPs) have been synthesized on the basis of ferric chloride-catalyzed oxidative coupling polymerization of muRi-thienyl monomers. The structures of ThPOPs were confirmed via solid-state t3C CP/MAS NMR spectroscopy and Fourier-transform infrared spectroscopy. The ThPOPs possess high porosities and their high Brunauer-Emmett-Teller specific surface area results vary between 350 and 1320mZg . The presence of abundant ultra-micronores at 0.50-0.63 nm allows ThPOPs efficient gas (carbon dioxide, methane, and hydrogen) adsorption. 展开更多

Conjugated porous polymers exhibit considerable advantage as attractive candidate for carbon dioxide(CO_(2)) capture. However, the regeneration of the CO_(2) still faces the problem of high energy cost. Here we synthesize a near-infrared region(NIR) light responsive conjugated porous polymer(PDPP-Gu) [DPP=3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione] by constructing porous amorphous networks with a side chain engineering strategy to regulate CO_(2) adsorption and release through photothermal conversion. The PDPP-Gu is featured by a torsional conjugated backbone as well as a functional side chain of guanidino group. The donor-acceptor configuration of PDPP-Gu afforded strong absorption in the NIR and an excellent photothermal conversion capability of up to 48.8%, as well as a high surface energy. Moreover, guanidine modified side chain further enhanced the CO_(2)-polymers interactions, resulting in a high CO_(2) selective adsorption capacity(0.8 mmol/g) at 273 K, 1 bar(1 bar=105 Pa). The adsorbed CO_(2) can be released under NIR light irradiation. This strategy of molecule design combined the dual features of photothermal conversion and gas adsorption, which is beneficial for the development of materials to dynamically control the adsorption and release of CO_(2) through NIR light. 展开更多
