A series of conjugated microporous polymers (CMPs) were synthesized via palladium-catalyzed Sonogashira-Hagihara crosscoupling polycondensation of N,N-bis(4-bromobenzyl)amine and 1,3,5-triethynylbenzene in different ternary solvents. The globular, tubular and amorphous CMP networks with different BET (Brunauer-Emmett-Teller) surface areas were obtained. Take advantages of superhydrophobic/oleophilic properties and microporous morphological structures of the resulting CMPs, a CMPs-based mesh film and a flexible, superhydrophobic, transparent CMPs-based film were prepared, which exhibit good oil/water separation performance and moderate transmittance. In addition, due to its abundant porous feature and unique chemistry nature of the as-prepared N-containing CMPs, the removal of the dyes from water and iodine from organic solvent have been investigated. The results show that the CMP-3 possesses the highest adsorption capacities of 269 mg g(-1) for rhodamine B, 198 mg g(-1) for methyl orange and 218 mg g-1 for iodine, respectively. This work provides a useful guidance for design and construction of porous CMPs materials for special applications. (C) 2016 Published by Elsevier B.V.
