| Summary: | Phthalocyanines are synthetic dyes which are shown to be good photoconverters which can be
applied in a photoelectrochemical cell constructed of semiconducting and metallic electrodes. By means of
spectroscopic investigation (absorption,fluorescence and photoacoustics) we have followed spectral properties
of phthalocyanines complexed with metals dissolved in polyvinyl alcohol solution in order to determine
the pathways of deactivation of their excited states. Spectroscopic investigations were accompanied with
photovoltaic/photocurrent and current-voltage characteristics of the photoelectrochemical cell with dyes. It
has been shown that there is a correlation between dye fluorescence feature and dye ability to electric photoconversion.
The comparison of new data for metallic phthalocyanines with those obtained for porphyrins
is discussed. |
