Investigation of high-performance adsorption for benzene and toluene vapors by calix[4]arene based organosilica (CBOS)

Calix[4]arene based organosilica (CBOS) was successfully prepared, characterized, and used for the adsorption of benzene and toluene vapors for the first time. The benzene and toluene vapor uptake of CBOS was determined to be 606 and 672 mg g⁻¹, respectively.
