Highly Luminescent Host-Guest Systems Based on Zeolite L and Lanthanide Complexes
Supramolecular incorporation of lanthanide complex has been obtained by loading of organic ligand into Eu<3+>-exchanged zeolite L. This was achieved by a two-step procedure: (1) zeolite L was ion-exchanged with Eu(Ⅲ) ions;(2) organic ligand was then loaded into the channels of the Eu<3+>-exchanged zeolite by gas diffusion procedure. Loading of ligand into the channels of zeolite L was confirmed by element analysis. Luminescence spectroscopy has confirmed that lanthanide complex are formed in the nanochannels of zeolite L crystals. In addition to the sharp emissions of lanthanide ions, broad band ranged from 350~500nm can also be observed. This study provides alternative method for fabricating full-color display materials.
