Abstract:
The role played by the peripheral substituent and the solvent on the
aggregation and photochemical properties of copper(II) phthalocyanine
and copper(II)phthalocyanine-3,4',4'',4'''-tetrasulfonic anion [Cu(tsPc)-4]
in aqueous solution has been studied by resonance Raman spectroscopy
(RRS). The vibrational mode ν&sub4; (1530 cm-1) and the symmetric
and antisymmetric stretching modes of water have been used as a probe
of interactions and aggregation in resonance Raman measurements. It
has been shown that the Cu(tsPc)-4 molecules have a tremendous
influence on water properties in solutions. In contrast, the influence
of water on the Cu(tsPc)-4 properties appears to be weak.
