In the title compound, [Cu(C12H8N2)(C7H4SO5)(H2O)]·C3H7NO, the CuII atom has a square-pyramidal coordination geometry formed by three O atom and two N atoms. The 1,2-di-4-pyridylethyl­ene ligands function as μ2-bridging ligands to form a zigzag chain. The 2-sulfonatobenzoate ligands protrude on alternate sides of the chain. Inter­molecular O—H⋯O hydrogen bonds link the chains into a two-dimensional network structure. [ABSTRACT FROM AUTHOR]

In the polymeric title compound, [Cu(im)Cl(phen)]n, where im is the imidazolate anion (C3H3N2) and phen is 1,10-phenanthroline (C12H8N2), each CuII ion is five-coordinated by four basal N atoms (two from two different im anions and two from one phen ligand) and one axial Cl atom, in a distorted square-pyramidal coordination geometry. Moreover, each im anion bridges two identical {CuCl(phen)}+ cations through its two N atoms, resulting in a one-dimensional zigzag chain along the crystallographic a axis. In addition, pairs of adjacent chains are staggered by π-π interactions, generating a two-dimensional layer, and neighbouring layers are further linked by two different kinds of C-H…Cl interactions, producing a three-dimensional network.

In the title compound, [Cu2(C8H4O5)2(C12H8N2)2(H2O)2]·3H2O, the Cu complex forms a centrosymmetric dimer with a Cu⋯Cu separation of 8.198 (3) Å. In the 5-hydroxy­isophthalate ligands, two carboxyl­ate groups coordinate two copper(II) cations in μ2-bridging bidentate coordination modes. [ABSTRACT FROM AUTHOR]

The title compound, C16H20N2S4, was synthesized by the reaction of 1,4-dibromomethylbenzene and 1,3-thiazine-2-thione. The molecule is located on a crystallographic centre of inversion. The thiazine ring has an envelope conformation. [ABSTRACT FROM AUTHOR]

The title compound, C18H8Cl2F3N5O2, is a tricyclic imide with an overall U-shape, each of the the three rings being planar. [ABSTRACT FROM AUTHOR]

Abstract: We studied the photoluminescence (PL) properties of self-organized para-sexiphenyl (PSP) nano-needles with linear and nonlinear optical excitation. Excited by femtosecond pulses, two-photon absorption (TPA) induced PL emission peaks corresponding to the vibronic transitions in PSP molecules were observed. Polarization-dependent photoluminescence measurements reveal that the TPA induced PL in the highly-ordered structures, similar with the linear excitation case, is strongly dependent on the excitation polarization. The mechanism that the nonlinear transition dipole moment is oriented parallel to the long axis of the molecular for the π–π∗ absorption in PSP is suggested to explain these strong polarization effects.
