Preparation and optical properties of novel symmetrical hexadecachlorinatedphthalocyaninato zinc(II) spin coated thin films

Abstract

Novel symmetrical 1,4,8,11,15,18,22,25-octahexyloxy-2,3,9,10,16,17,23,24-octa-(3,5- dichlorophenoxy)phthalocyaninato zinc(II) was synthesized and characterized by 1H NMR, 13C NMR, MS, UV-Vis, XRD, and IR spectrometry. The synthesized ZnPc complex is soluble in various organic solvents such as CH2Cl2, THF, acetone, and ethyl acetate. This property helped to obtain thin films of the new ZnPc complex by spin coating method. The surface morphology of the thin films was investigated by atomic force microscopy, AFM, and showed that the molecules grow in stacks of rows. The spectrophotometric measurements of transmittance (T) and reflectance (R) spectra were carried out in the wavelength range 190-3000 nm. © 2007 Elsevier Ltd. All rights reserved.
