摘要：

The protonated forms of six amino acids (glycine, L-alanine, L-tryptophane, L-histidine, L-methionine and L-lysine) were ion-exchanged into Na-montmorillonite. A comparison of the FT-IR spectra of the host, the guests and host-guest substances revealed that the guest ions were intercalated successfully. It was verified by X-ray diffractometry and surface measurements as well. The spatial arrangement of the guest ions was modeled by semiempirical quantum chemical method. The intercalated organic ions provide chiral environment within the layers of the host material. (C) 2003 Elsevier Science B.V. All rights reserved.
