A new type of functionalized cryptand-like ionophore. Synthesis, structure and complexation
Abstract
New functionalized cryptand-like ionophores are prepared from appropriate diaza-crown ethers and epichlorohydrin, using FAB MS, potentiometry, 13C-NMR spectroscopy, and T1 relaxation times measurements, the conformation and complexation patterns are found to change dramatically with the change in size of the macrocycle.
