Calix[4]tubes and Calix[4] semitubes A new class of ionophore

Journal article

The development of a novel class of ionophore based on bis-calix[4]arene molecular structures, the calix[4]tubes and the structurally related calix[4] semitubes, is reviewed in this chapter. The parent system exhibits remarkable selectivity for potassium over all group 1 metal cations and barium. Metal cation selectivity and rates of complexation can be further tuned via upper-rim substituent variation and by the nature of the lower-rim bridging linkages. The incorporation of quinone redox-ac...
