Abstract
Inclusion complexation of β-cyclodextrin (β-CD) with N-phenylphenothiazine ( 1), N-benzylphenothiazine ( 2) and N-phenethylphenothiazine ( 3) has been studied by means of UV-vis spectroscopy and molecular dynamics simulations. The association constants (Ka) were determined to be 126, 312 and 211 dm3/mol for inclusion of β-CD with 1, 2 and 3, respectively. It shows that the Ka values are affected by the substituents of the guest compounds. The structures of the complexes and the conformation of the guest compounds bound by β-CD in the complex have been discussed.
