a Adsorption isotherms of N2, CO2 and THF vapor. b Schematic illustration of an adsorption experiment where the activated powder of racemic D6H is exposed to various solvent vapors for 3 days. c TGA curves of the activated powder of racemic D6H before and after the adsorption of various solvents (scan rate = 10 °C/min). The adsorption capacities are listed in the inserted table. d Crystal diagrams of THF@D6H and NCI map for the intermolecular interactions between THF and D6H molecules. e Adsorption of THF by the activated powder of racemic D6H upon multiple adsorption-desorption cycles. Insets are the corresponding SEM images of the powder sampled from the adsorption-desorption cycles. f 1H NMR (500 MHz, CDCl3) spectra of the activated powder of racemic D6H after adsorption of DOX, CYH and a blend vapor of DOX with CYH.
