Homolog mixture of basic molecules of cucurbiturils has been synthesized and cucurbituril (CU) and cucurbituril (CU) have been isolated by means of solvent extraction. Inclusion complexes of different acid, reactive and disperse dyes have been produced by them. CU was decidedly more efficient in complex formation with all the studied dyes than CU. Competitive complex formation between randomly methylated ß-cyclodextrin and the respective cucurbiturils with disperse dyes has been studied and superiority of CU could be demonstrated. The complex forming efficiency of the cucurbiturils with acid and reactive dyes was markedly increased in the presence of Ca, Mg, K and Na ions, respectively, in water solution.
