The synthesis and spectroscopic characterization of zirconium(IV) dicarboxylate 1 and metallocavitand 2 are described. Encapsulation studies of fullerenes C-60 and C-70 were performed using UV-Vis spectroscopy in chlorobenzene, toluene, benzene, carbon disulfide and in a mixture of toluene/dichloromethane. UV-Vis titrations have shown that the binding abilities of the hosts toward fullerene C-70 are considerably higher than those obtained for fullerene C-60. (C) 2014 Elsevier B.V. All rights reserved.
