5-ethoxymethyl-8-hydroxyquinoline was synthesized and characterized using spectroscopic methods ( 1 H, 13C NMR, IR). The crystal structure determined at room temperature (295 K) by means of X-ray powder diffraction is orthorhombic, with space group Pbca and eight molecules per unit cell (Z = 8, Z 0 = 1). The lattice parameters are: a = 7.9551(12) Å , b = 17.981(3) Å , c = 15.125(2) Å and V = 2163.5(6) Å 3 . Geometric parameters and properties depending on the charge distribution around the different types of donors and acceptors bonds within the molecule are calculated by density functional theory (DFT/B3LYP) and Hartree-Fock methods. Atomic charges and dipole moment value permit qualitative predictions about high reactivity of this molecule. The 5-ethoxymethyl-8-hydroxyquinoline adopts a non-planar structure in the solid state and the molecule is stabilized by contact system as p-p stacking interactions, weak intra and intermolecular H-Bonding O-HÁÁÁN and C-HÁÁÁO types, this latter involving the rings of both adjacent molecules in plans with a gap from 0.638 Å .

“…In the last few years several methods, such as: sputtering [1], molecular beam epitaxy [2], metal-organic vapor deposition [3], pulsed laser deposition [4,5], spray pyrolysis [6,7] and sol-gel process [8][9][10] have been applied for thin films of zinc oxide depositing. In comparison to other methods, sol-gel has some evident advantages, i.e.…”

This work contains investigation results of the linear and nonlinear optical properties of metallophthalocyanines (Cu, Co, Zn, and Mg) and metallophthalocyanine chlorides (Al, Ga) thin films which were grown by physical vapor deposition (PVD) technique in high vacuum on transparent (quartz) and semiconductor (silica) substrates. Spectral properties of these films were examined using transmission, SGH and THG technique. Structural properties were investigated by AFM measurements. Transmission spectra were shown a large influence of intermolecular interaction on spectral properties of metallophthalocyanines and metallophthalocyanine chlorides. The influence of films thickness and annealing process of samples on their optical properties were also determined. The thickness dependence was connected with morphology of the film while annealing was caused change in polymorph phase. The measurements of transmission, SHG and THG spectra were allowed to determine optical constant of these films.
