Abstract
Tetrakis(diisopropyl amide) substituted norbornadiene and quadricyclane derivatives were investigated for their extraction and transport capabilities with alkaline earth metal cations. Both amides exhibited a remarkably high preference of Ba(2+) over any other alkali metal or alkaline earth cation. The binding geometries were determined by quantum chemical DFT calculations.
