Rational design of a novel indole-based microporous organic polymer: enhanced carbon dioxide uptake via local dipole-pi interactions ×÷Õß:Chang, GJ (Chang, Guanjun)[ 1 ] ; Shang, ZF (Shang, Zhenfang); Yu, T (Yu, Tao); Yang, L (Yang, Li)[ 1 ] JOURNAL OF MATERIALS CHEMISTRY A ¾í: 4 ÆÚ: 7 Ò³: 2517-2523 DOI: 10.1039/c5ta08705h ³ö°æÄê: 2016 ²é¿´ÆÚ¿¯ÐÅÏ¢ ÕªÒª An indole-based microporous organic polymer (PINK) has been obtained by the condensation polymerization of 1,3,5-tris-(4-fluorobenzoyl) benzene with 3,3'-diindolylmethane via a catalyst-free nucleophilic substitution reaction. Due to the local dipole-p interactions between indole and carbon dioxide (CO2), the uptake capacity for CO2 reaches up to 16.0 wt% (1.0 bar, 273 K), and the high (CO2/N-2 = 15, CO2/CH4 = 32) selectivities of the polymer make it a promising material for potential application in gas separation. Furthermore, the hydrogen storage is up to 2.48 wt% (1.0 bar, 77 K). In comparison to the reported porous organic polymers, the preparative strategy exhibits cost-effective advantages, which are essential for scale-up preparation. Its good performance for H-2 storage and CO2 separation suggests that PINK with a large specific surface area shows potential use in clean energy applications and the environmental field. ¹Ø¼ü´Ê KeyWords Plus:HYDROGEN STORAGE; SURFACE-AREA; INTRINSIC MICROPOROSITY; ENERGY APPLICATIONS; CO2 CAPTURE; CATION-PI; ADSORPTION; FRAMEWORKS; NETWORKS; POROSITY ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Chang, GJ; Yang, L (ͨѶ×÷Õß) ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ Southwest Univ Sci & Technol, State Key Lab Cultivat Base Nonmetal Composite &, Mianyang 621010, Peoples R China. µØÖ·: ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 1 ] Southwest Univ Sci & Technol, State Key Lab Cultivat Base Nonmetal Composite &, Mianyang 621010, Peoples R China ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 2 ] Southwest Univ Sci & Technol, Sch Mat Sci & Engn, Mianyang 621010, Peoples R China µç×ÓÓʼþµØÖ·:gjchang@mail.ustc.edu.cn; yanglichem628@126.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ National Natural Science Foundation of China 21202134 11447215 21504073 Project of Research and Development of Applied Technology of Mianyang City of China 14G-01-3 Open Project of State Key Laboratory Cultivation Base for Nonmetal Composites and Functional Materials 11zxfk26 14tdfk03 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ ROYAL SOC CHEMISTRY, THOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLAND Àà±ð / ·ÖÀà Ñо¿·½Ïò:Chemistry; Energy & Fuels; Materials Science Web of Science Àà±ð:Chemistry, Physical; Energy & Fuels; Materials Science, Multidisciplinary ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000369665800017 ISSN: 2050-7488 eISSN: 2050-7496 QQ½ØÍ¼20170624090615.png |
