Conjugated Porous Networks Based on Cyclotriveratrylene Building Block for Hydrogen Adsorption

Abstract Macrocyclic CTV‐Br 3 reacted with the linear benzene‐1,4‐diboronic acid and 1,4‐diethynylbenzene via Suzuki and Sonogashira‐Hagihara coupling reactions producing the rigid porous materials CTV‐CMP‐1 and CTV‐CMP‐2 . The porous materials have good thermal and chemical stability. The Brunauer‐Emmet‐Teller specific surface areas of CTV‐CMP‐1 and CTV‐CMP‐2 are 314 and 218 cm 2 ·g −1 , respectively. Physical properties of the porous materials were investigated, CTV‐CMP‐1 showed moderate hydrogen adsorption about 0.81 wt% at 1.13 bar while CTV‐CMP‐2 showed lower hydrogen adsorption about 0.51 wt%. These materials are analogs to activated carbons which could be potentially used in gas separation and organic compound adsorption.
