✦ Synopsis

The fluorescence of tetrakis(sulfonatopheny1) porphyrin (TPPS) and its photophysics were studied in a number of homogeneous solvents and Triton X-100 micelle. Enhancement of fluorescence quantum yields are discussed on the basis of polarity and viscosity of the solvents. Rotational correlation times rR were measured, using fluorescence anisotropy to show rigidization of the TPPS by the local environment of the micelle.

## Abstract In this paper it is shown that the charge transfer kinetics of the oxidation of sodium dithionite at a gold electrode in alkaline solution can be increased by modifying this electrode with cobalt(II)tetrasulfonated phthalocyanine, sodium salt (CoTSPc) or 5,10,15,20‐tetrakis‐(4‐sulfonato
