Title: Nonlinear optical materials: Synthesis, characterizations, thermal stability and electro-optical properties

Abstract

Two series of thermal stable polyimides and polyimide/silica hybrid materials have been synthesized. The silica content in the hybrid materials was varied from 0 to 22.5 wt.% and SiO{sub 2} phase was well dispersed in the polymer matrix. The glass transition temperature (T {sub g}) and the decomposition temperature (T {sub d}) were in the range 226-382 deg. C and 345-499 deg. C, respectively, for materials. The polymer solutions could be spin coated on the indium-tin-oxide (ITO) glass or other substrates to form optical quality thin films. The electro-optic coefficients ({gamma} {sub 33}) at the wavelength of 832 nm for polymer thin films poled were in the range of 12-25 pm/V and the values remained well (retained > 85% for more than 100 h). The heat capacities of some materials were in the range of 0.9755-1.1821 J K{sup -1} g{sup -1} for the temperature 273 and 363 K. No thermal anomaly was found in this temperature range. Most of them showed high thermal stability.

  • A novel type of 'X-shaped' two-dimensional electro-optic (EO) chromophore with extended conjugation has been synthesized and characterized. This chromophore is found to exhibit a remarkably blue-shifted optical maximum (357 nm in CH{sub 2}Cl{sub 2}) while maintaining a very large first hyperpolarizability ({beta}). Hyper-Rayleigh Scattering (HRS) measurements at 800 nm provide a {beta}{sub zzz} value of 1840 x 10{sup -30} esu. Self-assembled thin films of this chromophore were fabricated via a layer-by-layer chemisorptive siloxane-based approach. The chromophoric multilayers have been characterized by transmission optical spectroscopy, advancing contact angle measurements, synchrotron X-ray reflectivity, atomic force microscopy, and angle-dependent polarized second harmonic generationmore » spectroscopy. The self-assembled chromophoric films exhibit a dramatically blue-shifted optical maximum (325 nm) while maintaining a large EO response ({chi}({sup 2}){sub 333} {approx} 232 pm/V at 1064 nm; r{sub 33} {approx} 45 pm/V at 1310 nm). This work demonstrates an attractive approach to developing EO materials offering improved nonlinearity-transparency trade-offs.« less
  • The reactivity of the [Mo{sub 7}O{sub 24}]{sup 6-} anion towards the structure directing-reagent piperazine (pipz) has been investigated and new synthetic routes to achieve the known (H{sub 2}pipz){sub 3}[Mo{sub 8}O{sub 27}] 1, (H{sub 2}pipz)[Mo{sub 3}O{sub 10}].H{sub 2}O 2, and (H{sub 2}pipz)[Mo{sub 5}O{sub 16}] 3 molybdenum(VI) containing compounds are proposed. The role of the pH on the stabilization of the different compounds and their interconversion pathways is discussed. Compounds 1 and 2 show photochromic behavior under UV excitation, related to the particular organization of the organic component around the mineral framework. Their optical properties are reported and commented. - Graphical abstract:more » Three organic-inorganic hybrid materials have been prepared from the investigations of the [Mo{sub 7}O{sub 24}]{sup 6-}/piperazine system in hydrothermal conditions. The role of the pH on the stabilization of the different polyoxomolybdate blocks in the materials i.e. 1/({infinity}) [Mo{sub 3}O{sub 10}]{sup 2-} and 1/({infinity}) [Mo{sub 8}O{sub 27}]{sup 6-} chains and 2/({infinity}) [Mo{sub 5}O{sub 16}]{sup 2-} layer has been investigated.« less
  • The structural and optical nonlinear features of the condensed layers at the air-water interface and Langmuir-Blodgett (LB) films of the substituted fullerene 1-benzyl-9-hydrofullerene-60 (C{sub 60}-Be) were investigated by {pi}-A isotherm, small angle X-ray diffraction (SAXD), and optical measurements. Pure C{sub 60}-Be molecules existed at the air-water interface in a bulk phase. A new type of two-chain amphiphilic molecule, 1, 10-bistearyl-4, 6, 13, 15-tetraene-18-nitrogen-crown-6 (NC), was used as an inert material to construct mixed C{sub 60}-Be/NC LB films of much better quality than the pure C{sub 60}-Be LB films. Our {pi}-A, UV-visible absorption, and SAXD measurements show that the structural improvementmore » in the mixed C{sub 60}-Be/NC LB films was realized by insertion of the C{sub 60}-Be molecules between the two hydrophobic chains of the NC molecules. The relatively large third-order nonlinear susceptibility {Chi}{sup (3)}{sub {chi}{chi}{chi}{chi}}(-3{omega}; {omega},{omega},{omega}) = 2.1 x 10{sup -11} esu was deduced by measuring third-harmonic generation in the mixed C{sub 60}-Be/NC LB films. 13 refs., 7 figs.« less
  • The structure of the pseudo ternary TeO{sub 2}-TiO{sub 2}BaO glasses was investigated by Raman and infrared spectroscopies. In the TeO{sub 2}-BaO system, glasses with low BaO content have a continuous network constructed by sharing corners of TeO{sub 4} trigonal bipyramids and TeO{sub 3+1} polyhedra having nonbridging oxygen atoms. In glasses containing 40% mol BaO, isolated structural units such as TeO{sub 3} are formed. However, TiO{sub 2} insertion can inhibit this structural change and favor a continuous network. We discuss the characterization of nonlinear optical process in these materials using Z scan technique. The highest nonlinear absorption values are obtained formore » titanium tellurite glasses emphasising the particularly significant role of the structural units in the optical response.« less
  • The title compound, {beta}-alanine zinc chloride-a new semiorganic nonlinear optical crystal was grown by slow evaporation technique. Single crystals of {beta}-alanine zinc chloride have been subjected to X-ray diffraction analysis to determine the crystal structure. The powder X-ray diffractogram of the crystal has also been recorded. The amount of carbon, nitrogen and hydrogen in the crystals was also estimated. Fourier Transform Infrared and Raman spectral measurements have been carried out on the grown crystals in order to identify the functional groups. The presence of hydrogen and carbon in the {beta}-alanine zinc chloride was confirmed by using proton and carbon nuclearmore » magnetic resonance spectral analyses. The percentage of zinc in the crystal was determined by atomic absorption spectroscopy. Optical behavior such as ultraviolet-vis-near infrared transmittance spectrum and second harmonic generation has been investigated. The mechanical strength and thermal behavior of the grown crystal have been analyzed.« less
