    Synthesis, crystal structure and NLO properties of a novel ruthenium(II) complex with unusual coordination mode2005Inngår i: Transition metal chemistry (Weinheim), ISSN 0340-4285, E-ISSN 1572-901X, Vol. 30, nr 7, s. 778-785Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A new Schiff base 4-[N-hydroxyethyl-N-(methyl)amino]benzaldehyde S-methyl dithiocarbazate (HL, where H is a dissociable proton) and the ruthenium complex [Ru(bpy)2L]PF6 (bpy = 2,2′-bipyridine) have been synthesized. The structural determinations of the ligand and its ruthenium complex, by X-ray crystallography, show that the ligand is coordinated as a monoanionic bidentate N, S-donor, forming a four-member chelate ring with a bite angle of 65.91°. The complex shows intense MLCT transitions in the visible region. Fluorescent and electrochemical properties have been also studied. The complex in DMF solution exhibited a strong two-photon absorption (t.p.a.) at 532 nm nanosecond laser pulses. The t.p.a. coefficient β, t.p.a. cross-section σ and the third-order optical nonlinearity χ(3) of the complex and the ligand have been determined by the Z-scan technique.

    Synthesis, crystal structure and two-photon property studies on a series of complexes derived from a novel Schiff base ligand2004Inngår i: Transition metal chemistry (Weinheim), ISSN 0340-4285, E-ISSN 1572-901X, Vol. 29, nr 6, s. 596-602Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A new Schiff base ligand derived from S-benzyldithiocarbazate and 4-[N-hydroxy ethyl-N-(methyl)amino]benzaldehyde (HL, where H is a dissociable proton) and its NiII, CuII, ZnII and PdII complexes were prepared and fully characterized. The structures of HL and Ni(L)2 were determined by X-ray diffraction analysis, which revealed that the geometry of the NiII ion is square-planar with two equivalent Ni=N and Ni=S bonds, and that the two neighboring molecules in two layers have weak contact. The electronic spectra and solution fluorescence of the ligand and the complexes were studied, and the quantum yields of single-photon fluorescence for the compounds were determined. The compounds possess two-photon absorption (t.p.a.) character and the t.p.a. coefficient β and t.p.a. cross-section σ were determined by the Z-scan technique. Especially, the Zn(L)2complex and the HL ligand exhibit intensive two-photon fluorescence (t.p.f.) at 800 nm laser pulses in the femtosecond regime.

    Two strong emitting coordination polymers with chain and ladder structures2003Inngår i: Transition metal chemistry (Weinheim), ISSN 0340-4285, E-ISSN 1572-901X, Vol. 28, nr 6, s. 707-711Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Two coordination polymers [Zn(Cabo)2(EtOH)2(4,4′-Bipy)]n(1), and [Zn2(Cabo)2(NO3)2(4,4′-Bipy)2]n(2) (Cabo = carbazolylacetate, 4,4′-Bipy = 4,4′-bipyridine) with chain and ladder structures, respectively, were prepared and characterized by X-ray single-crystal structural analysis. The results showed that the different anions of metal salts have a large effect on the construction of coordination frameworks. Both complexes show strong emissions in the solid state as well as high thermal stability.
