A remarkably flexible and selective receptor for Ba2+ amplified from a hydrazone dynamic combinatorial library.
A new [2+2] tetra-hydrazone macrocyclic receptor was significantly amplified in a dynamic combinatorial library upon templation with alkaline earth metal ions. After optimisation the product could be isolated in 95% yield and its interaction with ions was investigated by NMR and UV-Vis spectroscopy.
