COMPETITIVE INTERACTION BETWEEN BIS(STYRYL) DYES, DOUBLE-STRANDED DNA AND CUCURBIT[7]URIL

In this study the formation of supramolecular «guest-host» complexes bis(styryl) dyes based on di(benzo)- or di(phenilaza)- 18-crown-6 ether with cucurbit[7]uril and double-stranded calf thymus DNA in buffer was investigated. A study of competitive interactions in the ternary DNA-bis(styryl)dye-cucurbit[7]uril system was carried out. A complex formation was studied by using spectrophotometric and fluorometric titrations.
