There have been two effects of the external electric field influence on the diffraction efficiency of reconstructed holograms observed in the films of copolymers 4-[(2-nitrophenyl)diazenyl]phenyl methacrylate with octylmethacrylate, when holographic recording of the plane wave front for parallel and orthogonal orientation of polarization vectors of light beams was performed at room temperature. After recording at exposure with small energies, diffraction efficiency in the electric field formed by corona discharge decreases, while with large exposure energies, it increases. Diffraction efficiency and recording velocity are higher in copolymer with lower softening temperature. The first effect is caused by reorientation of the dipole moments of azobenzene isomer fragments in the electric field, while the growth of diffraction efficiency is explained by the increase in the amplitude of regular geometric relief of the film surface, which appears during formation of the polarization hologram.

A new azo compounds is prepared by coupling the diazonium salts of (2- Cyano aniline) with 1,3- dihydroxynaphthalene to form (E)-2-((2,4-dihydroxynaphthalen-1- yl) diazenyl)benzonitrile. The azo ligand was identified by: Mass, 1H-NMR, C13NMR,UV-Vis. and IR spectra, in addition to elemental analysis measurement. The chelate complexes were characterized by elemental analysis, magnetic susceptibility, Molar conductance, UV-Vis. and IR spectra. The geometry of metal complexes were proposed based on analytical and spectral data. Analytical data revealed that all the complexes exhibited 1:2 metal–ligand ratio. On the basis of magnetic susceptibility measurements, suitable geometry was proposed for each complex. IR spectra of complexes show that the ligand is coordinated to the metal ions in bidentate manner with Oxygen and Nitrogen donor sites of hydroxynaphthalene (OH) and azo Nitrogen, which suggest octahedral geometry for all complexes. Also, biological evaluation of all synthesized compound shows moderate to good activity against Candida albicans, as antifungal.
