  The effects of crystal structure on optical absorption/photoluminescence of bis(8-hydroxyquinoline)zinc

  摘要：

  In this paper, the trans formal ion processes of two types of bis(8-hydroxyquinoline)zinc: Znq(2) dihydrate and anhydrous (Znq2)4 were investigated by X-ray diffraction (XRD), infrared spectra (IR), scanning electron microscope (SEM), differential scanning calorimetry (DSC) and thermogravimetry (TG). The effects of crystal structure on optical properties of bis(8-hydroxyquinoiline)zinc were analyzed. Znq(2) dihydrate can be transformed into anhydrous (Znq(2))(4) during heating under vacuum. Reversal transformation occurs by the interaction between chloroform and (Znq(2))(4). But (Znq(2))(4) was partially transformed into Znq(2) dihydrate by the interaction between ethanol and (Znq(2))(4). The different molecular structure results in different crystal stacking and electronic structure, thereby affect its optical properties. (C) 2005 Elsevier Ltd. All rights reserved.

  It is now well known that zinc is crucial for the synthesis of nucleic acids and, consequently, for cellular division. However, Zn-67, the NMR-detectable isotope, is one of the isotopes most poorly studied by NMR. The strategy used for NMR studies is the substitution of Zn by Cd-113. In this work, we employed C-13, Cd-113 NMR (CPMAS), X-ray and DFT calculation in order to evaluate the Zn-Cd substitution using 8-hydroxyquinoline like prototype compound. Our results show that there are strong structural and electronics effects are involved in the substitution. (C) 2008 Elsevier B.V. All rights reserved.
• Photolysis of Zn(8-quinolinolate)2(H2O)2 in non-aqueous solution. Photoactivation of hydrolysis
  作者：Arnd Vogler

  日期：2014.7

  The octahedral complex Zn(8-quinolinolate)(2)(H2O)(2) in non-aqueous solvents (e.g. chloroform, cyclohexane) undergoes a photolysis: Zn(8-quinolinolate)(2)(H2O)(2) -> Zn(OH)(2) + 2 8-quinolinole. It is suggested that this photohydrolysis is facilitated by hydrogen bonding. The irradiation (lambda >340 nm) is absorbed by the ligand chromophore. The IL excitation is associated with a charge shift from the coordinated phenolate to the nitrogen of the pyridine ring. As a consequence, the phenolate loses its coordinating ability. The subsequent deactivation is accompanied by the reversal of the charge shift. The regenerated phenolate may now undergo protonation from an adjacent water ligand in competition with the re-coordination to Zn2+. This system represents a simple model for activation of water which is coordinated to zinc(II). In distinction to the enzymatic function the hydrolysis in our system is initiated by a light switch.
