“…The sublimated Zn‐phthalocyanine (black line in Figure ) shows the typical transmission spectrum with two strong absorptions, the first one in the UV region at about 300–400 nm (B band) and a second one in the visible part of the spectrum around 600–700 nm (Q band). B band arises from the deeper π‐levels → LUMO transition while the Q band is attributed to the π–π* transition from the highest occupied molecular orbital (HOMO) to the lowest unoccupied molecular orbital (LUMO) of the pi resonant system of the porphyrinic ring . The transmittance spectra corresponding to samples T1–T4 are dominated by the remaining phthalocyanine after plasma treatment, in good agreement with the results discussed in the previous section.…”

In this paper the fabrication of highly porous ZnO layers and 1D nanostructures by a vacuum and plasma etching combined protocol is presented. Zn-phthalocyanine (ZnPc) is utilized as a solid precursor to form the ZnO. First the ZnPc is sublimated in low argon pressure. Depending on the substrate temperature and microstructure, polycrystalline films or single crystal ZnPc nanowires are grown. These starting materials are then subjected to a remote plasma oxidizing treatment. Experimental parameters such as substrate position, plasma power, treatment duration and substrate temperature determine the microstructure and properties of the final ZnO nanostructures. The article gathers an in depth study of the obtained porous nanostructured films following scanning and transmission electron microscopy (SEM and TEM), X-ray photoelectron spectroscopy (XPS), X-ray Diffraction (XRD), UV-Vis transmittance and fluorescence spectroscopies.

“…The manipulation of the values of these absorption peaks is possible by varying the concentration of the solution of the film, which opens the way to the use of films as optical windows. 3 In this work, we examined the solutions of 2 and 4 by mixing according to the InClPc (x) −ZnPc (1−x) (which is indicated as 2 (x) 4 (1−x) in Figures 5 and 6) formula, to see how the effect of mixing the two different solutions will change this manipulation. A graphical representation of the films obtained by mixing two different solutions is shown in Figure 5.…”

Four metallo (zinc, copper, vanadyl, and indium) phthalocyanine derivatives bearing four aliphatic (hexylthio) groups were prepared from corresponding phthalonitrile compounds. The metallophthalocyanines were characterized with ultraviolet-visible spectroscopy (UV-Vis), proton nuclear magnetic resonance ( 1 H NMR), Fourier transform-infrared spectroscopy (FT-IR), and mass and elemental analyses techniques. Aggregation properties of metallophthalocyanines in solution were studied in varied concentration ranges. Thin films of metallophthalocyanines were obtained by spin coating technique. Optical measurements showed that transmittance values of metallophthalocyanine thin films obviously changed with respect to the metal ion in the phthalocyanines. Transmittance spectra of the phthalocyanines synthesized using different metal ions showed a variation of about 8% and 15% in transmittance spectra of the Q band region was obtained by mixing the two metal phthalocyanine (indium and zinc) solutions.

“…This is also clearly seen in Figure 4, in which the absorption spectrum is shown. There are studies showing that the amount of absorption in the Q band region can be adjusted by the concentration of the solvent and can be used for optical windowing purposes (9). In this study, it is seen that the use of different solvents is also effective in this region.…”

“…The spin coating method is one of the most commonly used processes for obtaining thin films of soluble Pc compounds containing substituent groups (6,7). In this method, the final film thickness and other properties of thin film depend on the solution properties (concentration, drying speed, solid ratio, and surface tension) and processing conditions (rotation speed) (8,9).…”

Peripherally β-naphthoxy-substituted palladium(II) phthalocyanine was synthesized from corresponding phthalonitrile compounds. The palladium(II) phthalocyanine was characterized with ultraviolet-visible spectroscopy (UV-Vis), fourier transform-infrared spectroscopy (FT-IR), mass spectrometry, and elemental analysis techniques. Thin films of palladium(II) phthalocyanine were prepared using different organic solvents by spin coating technique. Transmittance and absorbance spectra of the thin films were studied in the wavelength range of 200-1000 nm. Optical band gaps of palladium(II) phthalocyanine thin films were also calculated.
