Thin films of fluorinated groups substituted metallophthalocyanines as an optical material

Thin films of fluorinated groups substituted metallophthalocyanines as an optical material
In this study, we report the synthesis and characterization of palladium(II)phthalociyanine including fluoro-4′-hexylthio-benzyloxy groups for the first time. The optical properties of a series of pentafluorobenzyloxy and tetrafluoro-4′-hexylthio-benzyloxy metallo-phthalocyanines were studied. Thin films of these compounds were obtained by using spin coating technique. Optical transmittance of thin films was measured using a spectrophotometer in the wavelength range of 200–1000nm. Optical band gaps of thin films were also calculated. In addition, surface morphologies and thickness of the films were investigated by Scanning Electron Microscopy. Results showed that the transmittance, band gap and morphology of the films are highly dependent on the metals and substituted groups of the phthalocyanines.
