Abstract
A series of new 2-aminoethoxy and carbamoyloxy substituted calix[4]are nes and calix[6]arenes has been synthesized and used to complex Eu3+ a nd Tb3+ ions. Emissive complexes in methanol solvent are obtained. The Tb3+ complexes are strongly emissive from a terbium centered excited state. The excited states of the calix[6]arene complexes are less effe ctively quenched by the addition of water than are those having the ca lix[4]arene ligands.
