Peripheral substituent and solvent effects on the aggregation and photochemical properties of copper(II)phthalocyanine and copper(II)phthalocyanine-3,4', 4 , 4'''-tetrasulfonic anion
2004
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 v 4 (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.
