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 m2 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 (λmax: 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.

芴)制备的共聚物材料(TPOP-3 或 TPOP-5)的比表面积高于各自的均聚物。重力氢吸附等温线表明,在 1.13 巴和 77 K 条件下,氢吸附容量高达 1.07 wt%。此外,在这些聚合物中加入四苯基
乙烯分子可在固态下诱发高光致发光(λmax:530-610 nm)。由于四苯基
