Abstract: in this paper, we have studied the interaction between a nenthesized probe type host molecule, RhB-β-CDcn, and DNAas well as the effect of temperature upon thefunction of this probe using spectrum method. The mode of the interaction between probemolecule and DNA, the ability of their intercalation and the effect of temperature upon hostmolecule containing guest molecule were discussed. In addition, the mechanism ofrecognition between the host molecule and the guest molecules was also studied.

Key words: Rhodamine B-(alkylamino)-cyclodextrin, Host, Guest
