摘　　要：N (2 methyl anthraquinone)diaza 18 crown 6 was designed and synthesized. Photophysical properties of the coordination compound between the crown compound as ligand and europium ion was investigated. Selective excitation to the charge transfer band between the ligand and Eu(Ⅲ) emission from Eu(Ⅲ) ion was observed indicating that intramolecular energy transfer from the excited singlet of the ligand to Eu(Ⅲ) ion occurred. Luminescence decay measurement showed that encapsulation of Eu(Ⅲ) ion into the cavity of the crown moiety does not completely shield the Eu(Ⅲ) ion from interaction with solvent molecules since three water molecules are still coordinated to Eu(Ⅲ) ion in the Eu(AQ CW)(NO 3) 3·3H 2O consistent with elemental analysis.\;N (2 methyl anthraquinone)diaza 18 crown 6 was designed and synthesized.
