| Abstract: | Supramolecular systems of the host CP44 with a-naphthol, β-naphthol, 2,6-dihydroxyl naphthalene and 2,3-dihydroxyl naphthalen-6-sulfonic acid were studied by UV specttroscopy, fluorescence spectroscopy and synchronous fluorimetry. The supramolecular system stoichiometry is 1: 1 for all naphthalene derivative complex guests with host CP44. The complex formation reaction of CP44 with a-naphthol was promoted by heat content, where as the complex formation reactions of CP44 with β3- naphthol, 2,6-dihydroxyl naphthalene and 2,3-dihydroxyl naphthalen-6-sulfonic acid were promoted by entropy increase. It was proved that host CP44 can recognize the isomers, a-naphthol and β-naphthol by fluorescence probe. |
