Carbon dioxide capture in a self-assembled organic nanochannels

The uptake of carbon dioxide was studied in porous organic solid, p-tert-butylcalix[4] dihydroquinone, in which all calixarenes are self-assembled in a tubular fashion via strong hydrogen bonds. the BET surface area of porous material was found to be 230 m(2)/g. This represents another rare example in which purely organic crystals can be designed to store and separate gas mixtures.
