摘要: Four various phthalocyanines dyes were oriented in uniaxially stretched polymer films. Polarized absorption, fluorescence, and photoacoustic spectra measured. From a stepwise reduction procedure, the orientation of molecules with respect to film stretching direction as well absorption transition moments vectors molecular skeleton dye evaluated. The complexation metals attachment side groups phthalocyanine ring change orientations interactions chains. Two bands, B1 B2, different their found short wavelength spectral region. obtained results discussed on ground literature data compared our previously gathered concerning possible application investigated photodynamic therapy.
