Abstract
Derivatives of p-tert-butylcalix[4]arene substituted on the lower rim with fragments of aminopolycarboxylic acids (EDTA, DTPA) were obtained. Mono and binuclear complexes with lanthanide (III) ions were synthesized using these compounds. The effect of the number and type of aminopolycarboxylic acid fragments on the luminescence of ligands and complexes was studied. The influence of the distance between the emitting ion and the calixarene macrocycle on the intensity of 4f-luminescence was analyzed.
