摘要
Two d-f heterodinuclear cryptates Eu(Ⅲ)-M(Ⅱ)(M=Zn 2+, Ni 2+) were synthesized and characterized by elemental analysis, IR and ES-MS. The fluorescence properties of the cyptates in acetonitrile solution show that inclusion of Zn 2+ in the mononuclear europium(Ⅲ) cryptate increases the energy transfer between cryptand and europium(Ⅲ) ion, while the inclusion of Ni 2+ in the cavity quenches the fluorescence of Eu(Ⅲ) cryptate.
