Popis:	Two p-tert-butylcalix[4]arene derivatives were synthesized from the reaction of calixarene with epichlorohydrine and then its reaction of ammonia. These donor macromolecular compounds were interacted with iodine in chloroform and interaction was investigated by using a UV-visible spectrophotometer. The chargetransfer spectra of n-[sgrave] type interactions were observed at 362 nm and 369 nm. The stability constants and some thermodynamic parameters were found.
