Synthesis of conjugated microporous polymer nanotubes with large surface areas as absorbents for iodine and CO₂ uptake

Abstract

Conjugated microporous polymer nanotubes (CMPNs) were synthesized and employed as a platform for investigation of CO2 and I2 adsorption. A high adsorption capacity of up to 208 wt% for reversible I2 capture was achieved.

Synthesis of conjugated microporous polymers for gas storage and selective adsorption

“…The BCMP-1 and BCMP-2 were synthesized by Pb(II)/ Cu(I)-catalyzed Sonogashira-Hagihara cross-coupling polymerization from tetra(4-bromophenyl)methane and arylethynylene with different structures, which was proved as a reliable approach to construct CMPs networks [8,27]. The representative molecular structures for BCMP-1 and BCMP-2 are shown in 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].…”

Capture and reversible storage of volatile iodine by porous carbon with high capacity

“…Sigen et al reported a metalloporphyrin-based conjugated microporous polymer (CMP) with exceptional performance in the reversible adsorption of iodine [2]. In our previous work, we prepared CMP nanotubes as absorbents with an excellent uptake of 208 wt% for iodine capture, which is one of the highest values reported for porous materials [13]. However, in most cases, some disadvantages for these solid adsorbents are related to high-cost production and complicated fabrication process as well as the uncertain Electronic supplementary material The online version of this article (doi:10.1007/s10853-015-9289-1) contains supplementary material, which is available to authorized users.…”

Controlled synthesis of soluble conjugated polymeric nanoparticles for fluorescence detection

“…CMPs, a class of amorphous materials possessing three-dimensional networks with their building blocks linked in a p-conjugated fashion, have emerged as an important material platform since 2007. 27 Later on, they are extensively utilized in gas adsorption, [28][29][30][31] electrical energy storage, [32][33][34] and especially in chemosensors [35][36][37] owning to their high sensitivity and technical simplicity. However, the difficulty in processing and device integration have been considered as the Achilles heel for CMPs to be competitive in future applications.…”
