- A new kind of HMPs based on DDSQ was prepared through Friedel-Crafts reaction.
- The produced HMPs possess a maximum BET surface area of 923Â m2Â gâ1.
- TGA curves demonstrate that the HMPs had a very high thermal stability.
- The HPMs have a high gas storage capacity for CO2 and H2.
A series of hybrid microporous polymers (HMPs) were prepared through Friedel-Crafts reaction with double-decker-shaped silsesquioxane as the building block. The ratio between the monomer and the crosslinker has significant influence on the surface area and porous morphology. A maximum BET surface area of 923Â m2Â gâ1 and high gas storage capacity (CO2:10.4Â wt%, 273Â K/1.0Â bar; H2: 0.95Â wt%, 77Â K/1.0Â bar) were achieved. The obtained HMPs have high thermal stability due to the introduction of SiO bonds.
