摘要：

In aqueous solutions, 2-anilino-6-naphthalenesulfonic acid (2,6-ANS), 1-chloronaphthalene (1CN), and azulene (Az) form 1:1 inclusion complexes with a beta-cyclodextrin (beta-CD) moiety in poly-beta-cyclodextrin (poly-beta-CD). Equilibrium constants (K) for the formation of the inclusion complexes have been evaluated from the fluorescence intensity changes with concentration of poly-beta-CD. The K values for poly-beta-CD are similar to those for beta-CD In contrast to the behavior of beta-CD whose 1:1 inclusion complexes with ICN self-associate to form a 2:2 inclusion complex, the association does not occur between the beta-CD moieties on the same poly-beta-CD chain, indicating that poly-beta-CD exhibits a rather simple inclusion mode.
