  Zinc complexes of 1-Propyl-2-(2-tosylaminophenyl)-5-aminobenzimidazole: Synthesis, structure, and luminescence properties

  摘要：

  1-Alkyl-2-(2-tosylaminophenyl)-5-aminobenzimidazole and related zinc complexes are synthesized. The structure of the complex with zinc pivalate is determined by X-ray diffraction analysis. The fluorescence with the anomalous Stokes shift of the benzimidazole ligand system in solution is transformed into the fluorescence with the normal Stokes shift upon complex formation due to blocking the mechanism of intramolecular proton transfer in the excited state or upon the transition to the crystalline state formed by zwitterionic forms that are generated due to the proton transfer from the sulfonamide group to the amino group.

  A series of novel benzimidazole derivatives 1-alkyl-2-(2'-tosylaminophenyl)-5-nitrobenzimidazoles with common formulas HL (1-3) (R = C2H5 (1); R = n-C3H7 (2); R = n-C4H9(3)) and their mononuclear zinc(II) complexes ZnL2 (4-6) have been synthesized in a molar ratio Zn: HL = 1:2 in methanol solutions. Formulation of 1-6 is based upon satisfactory C, H, N, S elemental analyses, IR and H-1, C-13 NMR spectroscopies, while the structures of 2, 3, 5, 6 were determined by X-ray single-crystal diffraction. The optical properties of 1-6 were investigated. Published by Elsevier B.V.
