The tunable third-order optical nonlinearities of a diarylethene-zinc phthalocyanine hybrid

Synthesis and third-order nonlinear optical properties of a sandwich-type mixed (phthalocyaninato)(schiff-base) triple-decker complexes

“…However, the data in Table 1 clearly demonstrates that our sandwich-type complexes have excellent third-order NLO response. Compared to other hybrid phthalocyanine compound measured under analogous experimental conditions [9,10], the macroscopic two-photon absorption coefficient (b) for the sandwich-type complexes is not sufficiently large, implying these sandwich-type complexes are not optimal for optical limiting applications. Nevertheless, the large values of c (3) and figures of merit T ¼ 14 (FOM, T ¼ lb/n 2 [8]) are enabling for other NLO applications, such as wavelength conversion via fourwave mixing (FWM) and all-optical switching, respectively.…”

The crucial role of self-assembly in nonlinear optical properties of polymeric composites based on crown-substituted ruthenium phthalocyaninate

“…Dark blue crystals of solvate [(15C5) 4 Pc]Ru(pyz) 2 ·6CHCl 3 were obtained by slow evaporation of its solution in Please do not adjust margins Please do not adjust margins matrix least-squares technique on F 2 with anisotropic displacement parameters for all non-hydrogen atoms. All the hydrogen atoms in the complexes were placed geometrically and included in the structure factor calculation in the riding motion approximation.…”

“…This effect appears both in solutions of aggregated Pc's 3,4 and in films obtained by various techniques -cast, epitaxial growth, spin-coating, Langmuir-Blodgett, etc. Variation of substituents at the periphery of the Pc macrocycle, as well as the metal ion in its cavity and axial ligands, results in the appearance of a huge family of compounds, affording thereby fine tuning of required physicochemical characteristics.…”

“…16 The third-order nonlinear optical properties of this ruthenium(II) complex have been measured by means of Z-scan techniques in a tetrachloroethane (TCE) solution. Taking all these into account, we report here features of self-assembling and the optical behavior of composites of ruthenium(II) tetra-15-crown-5-phthalocyaninate containing axially coordinated molecules of pyrazine [(15C5) 4 Pc]Ru(pyz) 2 (1) with polyvinylcarbazole (PVC) measured by the Z-scan technique. 27 The morphology of these assemblies was investigated using atomic force microscopy, which demonstrated the presence of stable supramolecular wires 7-8 nm in height, 100-150 nm in width and 600 nm or more in length.…”

Three-dimensional display based on refreshable volume holograms in photochromic diarylethene polymer

“…The reversible change is achieved by the exposure at another wavelength. This characteristic of photochromic compounds makes them available in the field of rewritable holographic 3D display, avoiding the manipulation of high voltage electric field 7,8 .…”
