Abstract: The luminescence spectra of the supramolecular complex of an uranyl ion and a ring calix[8] arene polymer have been obtained. It has been found that a significant reconstruction of light-emitting levels takes place in the temperature range 130–180 K. It has been assumed that the observed features are due to excitation transfer between the uranyl ion and the complex-forming polymer.
