NMR analysis of Nile Blue (C. I. Basic Blue 12) and Thionine (C. I. 52000) in solution

The dyes Nile Blue (C. I. Basic Blue 12) and Thionine (C. I. 52000) were examined in both ionic and neutral forms in different solvents using NMR and UV-visible spectroscopy to firmly establish the structures of the molecules and to assess the nature and extent of their aggregation. 1H and 13C NMR assignments and chemical shift data were used, together with nuclear Overhauser effect information, to propose a self-assembly structure. These data were supplemented with variable temperature, dilution and diffusion-based experimental results using 1H NMR spectroscopy thereby enabling extended aggregate structures to be assessed in terms of the relative strength of self-association and the extent to which extended aggregates could form.

KINETICS OF THE (PHOTO)OXIDATION OF THE THIONINE LEUCO BASE WITH URANYL NITRATE

Spectrophotometry and lamp and laser flash photolysis have been used to investigate the kinetics of the formation and decay of thionine and semithionine, obtained in the photooxidation of the thionine leuco base with uranyl nitrate.It has been shown that after the light flash a certain amount of thionine is formed in the cage oxidation of semithionine with uranoyl UO2+ (concentration ratio of thionine and semithionine leaving the cage 5:95).A kinetic scheme of the reaction has been proposed, which describes satisfactorily the experimental data.The equilibriumconstant K=(1.2+/-0.3)*10-4 has been obtained for the dark oxidation of the thionine leuco base with uranyl nitrate in aqueous sulfuric acid (pH 1.0) which is close to the calculated value.

The Relation between Radical Yield and Free Enthalpy Change for Triplet State Electron Transfer Reactions in Acetonitrile

The electron transfer reaction from aromatic compounds without heavy atom substituents to triplet thionine has been studied in acetonitrile by an emission-absorption flash technique.The free radical yield ΦR was slightly less than unity in the range of the free enthalpy change of reaction, ΔG = -0.46 ca. - 0.16 eV, but it was close to unity in the other range of ΔG.This dependence of ΦR on ΔG is different from that in the excited singlet state reported by Iwa et al. - Keywords: Electron transfer reaction / Triplet state / Thione
