| Research Abstract |
A novel separation method for lanthanide utilizing pseudo-enantio selective coordination and molecular template was developed. The newly synthesized ligand PTA gives the complexes with each pseud-chiral conformation at the boundary of specific lanthanide. We found enantio-selective precipitation of lanthanide-PTA complex by utilization of molecular template. Furthermore, ion size recognition property of PTA can be controlled by modification of substituent, and specific lanthanide can be separated selectively utilizing two PTA derivatives which have different recognition properties.
