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.
