Porous organic polymers standing out from kinds of porous materials such as zeolite, activated carbon, metal-organic frameworks [1][2], and covalent organic frameworks [3][4], with their prominent
p-toluenesulfonic acid (TSA) as catalyst that has been proved to be a non-metallic acidic catalyst with high efficiency [26][27]. The materials exhibit Brunauer–Emmet–Teller (BET) specific surface area values ranging from 720 to 920 m2 g–1, and the highest carbondioxideuptake is up to 15.0 wt % at

10.3762/bjoc.12.185 Abstract Two hydroxy-functionalized hyper-cross-linked ultra-microporous compounds have been synthesized by Friedel–Crafts alkylation reaction and characterised with different spectroscopic techniques. Both compounds exhibit an efficient carbondioxideuptake over other gases like N2
uptake at 195 K encouraged us to perform a CO2 adsorption study at room temperature. HCP-91 and HCP-94 both exhibit an adequate amount of carbondioxideuptake at 273 K and 298 K (Figures S9 and S10, Supporting Information File 1). At 273 K the CO2 uptake was 74 mL/g for HCP-91 and 65 mL/g for HCP-94 at
