英文摘要: Abstract(#br)A combined experimental and computational study has been applied in order to understand the effect of the addition of subsequent methyl groups to chiral (1R,2S)-(−)-ephedrine on its structure-directing behavior during crystallization of the nanoporous AFI aluminophosphate. Results show that bare ephedrine and the double-methylated N,N-dimethyl-ephedrinium display the most efficient structure-directing abilities, while the mono-methylated derivative shows a poor structure-directing capacity towards this framework. Fluorescence spectroscopy indicates that confinement of the mono- and di-methylated derivatives within the nanopores of the AFI channels involves a preferential incorporation of the SDA molecules as monomers. In contrast, occlusion of the bare ephedrine can lead to a...
