Abstract

Macrocyclic CTV-Br3 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 cm2·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.
