“…Also, the values of  (3) are 10 -12 esu, which is compatible with other phthalocyanines [11][12][13]. The obtained results of  (3) and n2 indicate that TiPcCl2 films are excellent nonlinear optical materials, mainly if used as optical limiters.…”

“…The increase in the values of the three parameters with the increase in the thickness could be related to the change of the delocalization degree of πelectron and the aligned chains in the direction of the induced electric field [47]. Also, the values of  (3) are 10 -12 esu, which is compatible with other phthalocyanines [11][12][13].

Phthalocyanines are of a broad interest in photovoltaic applications. In this study, films of titanium-phthalocyanine-chloride (TiPcCl2) were prepared by the thermal evaporation method. The molecular structure was studied by Raman spectrometer, showing a match between the spectra of the powder and the prepared films. The films' surface was examined by the atomic force microscope, revealing grain size and surface roughness of TiPcCl2 thin films to be 223 and 41 nm, respectively, for a 100 nm thickness. The energy gap was determined to be 1.5 eV, with no observable effect by the thickness change. Additionally, the linear and nonlinear optical constants were calculated from reflectance and transmittance measurements. The values of third nonlinear susceptibility are in order of 10− 12 esu, which is compatible with other phthalocyanines. The nonlinear optical constants indicate that TiPcCl2 films could also be used for optical laser limiters.

“…The changes of n and k upon exposure to NH 3 in the row of MPcF 16 exhibit the same trend as the above discussed Among the huge variety of experimental techniques, vibrational spectroscopies (IR and Raman) have been shown to be very useful for study of the surface structure and properties of thin films[51][52][53][54][55]. These techniques are particularly suitable in the case of MPcF 16 compounds with unknown crystal structure, because the commonly employed X-ray diffraction methods cannot be applied directly in this case.Note, however, that the vibrational spectroscopy methods can give insight into the structure of thin films only provided that the detailed assignment of the vibrational spectra of the deposited species is available.…”

Highlights-The sensor response of fluorinated metal phthalocyanines toward NH 3 was performed.-The sensor response was studied using surface plasmon resonance technique.-The effect of central metal in MPcF 16 molecule to the sensor response was verified.-The structure of analyte/phthalocyanine complex was analysed using DFT calculations.3 A comparative study of the sensor response toward gaseous ammonia of hexadecafluorinated 3d-metal phthalocyanine (MPcF 16 , M=Cu(II), Co(II), Zn(II), Ni(II)) thin films was performed using complementary experimental (viz., surface plasmon resonance, SPR, and IR absorption spectroscopy) along with theoretical (density functional theory calculations, DFT) techniques. SPR measurements revealed changes of both thickness and optical parameters (refraction indices and extinction coefficients) of the MPcF 16 films caused by adsorption of NH 3 . The MPcF 16 species studied exhibited the following order of sensor response: ZnPcF 16 > CoPcF 16  CuPcF 16 > NiPcF 16 . A good correlation was found between the DFT calculated (B3LYP/6-311++G(2df,p)) binding energies, experimentally measured shift of the selected IR bands, and the optical sensor response. Apart from this, we performed a detailed assignment of all intense bands in the vibrational spectra (IR and Raman) of fluorinated 3d-metal phthalocyanines studied.

“…The higher binding energy value of 533.47 eV in the O 1s region can be attributed to the oxygen from the water molecules (Mercier et al, 2006). The lower energy peak at 531.72 eV can be assigned to the O contributing to the Ru-O-Ru component of the dimer (Basova et al, 2014). The binding energy values for photoelectron peaks of Ru and O are summarized in Table S4.…”

The results of the structural determination, magnetic characterization, and theoretical calculations of a new ruthenium-oxo complex, Li4[Ru2OCl10]·10H2O, are presented. Single crystals were grown using solvent methods and the crystal structure was characterized by single crystal X-ray diffraction. Li4[Ru2OCl10]·10H2O crystallizes into a low-symmetry triclinic structure (P 1) due to the much smaller Li+ cation compared to K+ cation in the tetragonal complex K4[Ru2OCl10]·H2O. The X-ray photoelectron spectra confirm only the single valent Ru4+ in Li4[Ru2OCl10]·10H2O even though two distinct Ru sites exist in the crystal structure. Magnetic measurements reveal the diamagnetic property of Li4[Ru2OCl10]·10H2O with unpaired electrons existing on Ru4+. Furthermore, the molecular orbital analysis matches well with the observed UV and magnetic measurements.
