通过Suzuki偶联缩聚或氧化偶联聚合，有效地合成了四苯乙烯基多孔有机聚合物。根据所获得的氮物理吸附等温线，这些多孔材料的Brunauer-Emmett-Teller比表面积值在472和810 m2/g之间变化。使用相同的连接体单体，由两种不同的核结构单体（四苯乙烯和螺二芴）制备的共聚物材料（TPOP-3或TPOP-5）的比表面积高于相应的均聚物的比表面积。氢吸附等温线表明，在1.13bar和77 K下，吸附量可达1.07wt%。此外，掺入到这些聚合物的四苯乙烯部分可以诱导在固态下的高光致发光（λ（最大）：530-610 nm）。由于四苯乙烯的螺旋桨状结构和聚集诱导发射特性，它有望成为设计具有特殊性能的多孔聚合物的一种很有前途的结构单元。
Tetraphenylethylene-based porous organic polymers were synthesized efficiently through a Suzuki coupling polycondensation or oxidative coupling polymerization. According to the obtained nitrogen physisorption isotherms, the Brunauer-Emmett-Teller specific surface area values for these porous materials vary between 472 and 810 m(2) g(-1). Using the same linker monomer, the specific surface area of copolymer materials (TPOP-3 or TPOP-5) prepared by two different core structural monomers (tetraphenylethylene and spirobifluorene) is higher than those of the respective homopolymers. Gravimetric hydrogen adsorption isotherms show that the adsorption capacity for hydrogen is up to 1.07 wt% at 1.13 bar and 77 K. Furthermore, incorporation of tetraphenylethylene moieties into these polymers can induce high photoluminescence (lambda(max): 530-610 nm) in the solid state. Thanks to the propeller-like structure and aggregation-induced emission characteristics, tetraphenylethylene is to be a promising building block for designing porous polymers with special properties.
