Abstract

Abstract: When adding thionine to alcoholic solution of trisacetylacetonate manganese (Ⅲ), the UV spectrum is red shifted and a new peak around 340 nm is observed. Meanwhile a characteristic Stern-Volmer plot is obtained for the system in which static and dynamic quenching is active. Therefore experimental evidences are provided for the association interaction between the species in ground state.

Key words: thionine, trisacetylacetonate manganese (Ⅲ), static quenching, dynamic quenching, ground complex
