  Simplest Homoleptic Metal-Centered Tetrahedrons, [M(OH₂)₄]²⁺, in 1-Ethyl-3-methylimidazolium Tetrafluoroborate Ionic Liquid (M = Co, Ni, Cu)

  摘要：

  Dissolution of a tetrafluoroborate or perchlorate salt of [M(OH2)(6)](2+) (M = Co, Ni, Cu) in 1-ethyl-3-methylimidazolium tetraluforoborate ionic liquid ([emim]BF4) results in significant solvatochromism and increasing intensity of color. These observations arise from partial dehydration from the octahedral [M(OH2)(6)](2+) and formation of the tetrahedral [M(OH2)(4)](2+). This reaction was monitored by the intense absorption band due to the d-d transition in the UV-vis absorption spectrum. The EXAFS investigation clarified the coordination structures around M2+ {[Co(OH2)(4)](2+), R(Co-O) = 2.17 angstrom, N = 4.2; [Cu(OH2)(4)](2+), R(Cu-O) = 2.09 angstrom, N = 3.8}. H-1 and F-19 NMR study suggested that both [emim](+) and BF4- are randomly arranged in the second-coordination sphere of [M(OH2)(4)](2+).

  A [Ni(cyclam)]2+-functionalised poly(3,4-ethylenedioxythiophene): Synthesis, electropolymerisation and characterisation of the polymer by cyclic voltammetry and in situ reflectance FTIR spectroscopy

  摘要：

  A 1,4,.8,11-tetraazacyclotetradecane (cyclam) derivative of 3,4-ethylenedioxythiophene (EDOT) has been synthesised. Its square planar Ni(II) tetrafluorobo rate complex has been electrochemically polymerised, with EDOT itself, to give a highly stable conducting polymer with covalently attached [Ni(cyclam)](2+) Moieties. The cyclic voltammogram shows redox behaviour typical of a functionalised PEDOT, with the reversible Ni(II)-Ni(III) process of the [Ni(cyclam)](2+) complex superimposed. Reflectance in situ FTIR spectroscopy (RIFTIRS) shows that the presence of the metal complex has a profound influence upon the behaviour of the electronic band of the oxidised form of the polymer, and of the vibrational signature due to the charge carriers.
