| Outline of Final Research Achievements |
The objective of this research is to develop a selective synthesis method for hetero-trinuclear lanthanide-thiacalixarene complex. The intermediates, Tb1TCAS1 or Yb1TCAS1 complex, could be isolated by preparative liquid chromatography. In the case of Yb1TCAS1, Tb1Yb2TCAS2 complex formed selectively by the addition of Tb solution into the isolated Yb1TCAS1 sample. On the other hand, the mixture of homo- and hetero-trinuclear Ln-TCAS complex showed luminescence in visible region by near-infrared excitation. This result indicates up-conversion luminescence by f-f communication.
