Photophysical properties of [60]fullerenes and phthalocyanines embedded in ordered mesoporous silica films annealed at various temperatures
Article Abstract:
The photophysical properties of fullerene and/or phthalocyanice dyes embedded in ordered mesoporous silica films and the influence of annealing temperature on the nature of the immobilized dye molecules are investigated using photoluminescence and diffuse reflectance studies. The extent of aggregation of fullerenes supported on amorphous silicon oxide films is shown to depend on the annealing temperature.

Electron-transfer kinetics in sulfonated aluminum phthalocyanines/cytochrome c complexes
Article Abstract:
The fluorescence of sulfonated aluminum phthalocyanines is greatly reduced in the presence of cytochrome c through the formation of 1:1 complexes and a photoinduced electron-transfer. The average unimolecular electron-transfer rate constants being higher for the tetrasulfonated dye indicates a tighter complex and a shorter distance between donor and acceptor moieties.

Interactions of a sulfonated aluminum phthalocyanine and cytochrome c in micellar systems: binding and electron-transfer kinetics
Article Abstract:
The interaction of the tetrasulfonated aluminum phthalocyanine with cytochrome c has been studied. High-electron transfer rate constants have been obtained in cyclohexane/n-hexanol/Triton X-100/water microemulsions, and the rate constants could not be attributed solely to a more-viscous environment.
