Abstract
A novel macrocyclic compound-water soluble functional calixresorcin[4]arene s-tetra para sulfo-phenylmethyl-calixresorcin[4]are was synthesized for the first time. The photophysical properties of terbium and europium ions enca psulated in the macrocyclic ligand were studied in detail. The triplet stat e energy of the calixresorcin[4]arene was determined to be 24400 cm(-1) by the low temperature phosphorescence spectrum and it was found that it can s ensitize both terbium ion and europium ion. The possible energy transfer pr ocess between the functional calixresorcin[4]arene and the encapsulated Tb3 + and Eu3+ was discussed. The luminescence quantum efficiency of Tb3+- cali xresorcin[4]arene was calculated.
