A new class of calix[4]arene crown ethers with one or two bipyridines appended to the polyether ring (lariat calixcrowns) have been designed and synthesized; the luminescence properties of their Eu3+ and Tb3+ complexes have been studied in acetonitrile. In this solvent, long lifetimes for the metal emitting states and high metal-luminescence intensities obtained upon ligand excitation have been observed in both Eu3+ and Tb3+ complexes. The association constants in methanol have been determined for some of the complexes studied.

The triol (VII), an analogue of Tris, has been synthesized and has been used as a convenient primer for the synthesis of triantennary trityl ethers the use of which as terminators in trityl-cyanoethylidene polycondensation has permitted the synthesis of a
