Study of resonance effects in copper phthalocyanines
چکیده انگلیسی

The purpose of this paper is to follow the influence of chlorine or fluorine substituents of phthalocyanine dyes on their spectroscopic, photothermal and photoelectric properties. Such influence is discussed in term of the resonance effects occurring in organic macrocycles. The domination of mesomeric effect was indicated due to the large enhancement of photocurrent created by the studied systems and other changes in spectroscopic and photothermal properties of the investigated phthalocyanines. The occurrence of steric effect was supported by the photothermal experiments. The differences between electronegative substituents of phthalocyanine dyes on photophysical properties of macromolecular systems are also discussed.
