Abstract

Metallophthalocyanine complexes (M = Pd, FeCl, VO, or MnCl) bearing four hydroxyl-terminated aliphatic groups were prepared by cyclotetramerization 4-(hydroxyethylsulfanyl)phthalonitrile. Aggregation tendencies of these phthalocyanines were investigated in varying concentrations from 4 x 10(-5) to 8 x 10(-6) M in DMF. Spin coating method was used to prepare thin films of metallophthalocyanines substituted with four hydroxyethylsulfanyl groups. The optical properties of the films were investigated as a function of the different metal ions in the inner core, with the transmittance spectrum measured at a wavelength range of 200-1000 nm. The results show that different metal ions in the inner core clearly change the transmittance values of the thin films of metallophthalocyanine. Morphological results also show that surface of the metallophthalocyanines has changed considerably according to the nature of the metal ion.
