摘要：

Chiral microporous lanthanide silicates Na3[(Y,Ln)Si 3O9]·3H2O (1; Ln = Eu, Tb, Er, Ce) have enantiomeric domains that can be discriminated by means of Eu3+ photoluminescence spectroscopy. In the framework of 1 (see picture), (Si 3O9)∞ spiral chains interconnect the {(Y,Ln)O6} octahedra, and channels along [100] contain Na+ ions and water molecules. Color code: {(Y,Ln)O6} yellow; {SiO 4} green; O red; Na purple; H white. (Figure Presented) © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
