    Notes: A straightforward and generalizable synthesis of metal-free and metal (Ni, Pb, Lu) derivatives of symmetrically tetrasubstituted phthalocyanines derived from 15, 16-dibromo- or -dicyano-2, 3, 6, 7, 8, 9, 11, 12-octahydro-5H-benzo[e][1, 4, 7, 13]tetroxaza-cyclopentadecine (1) is described. Quaternarization of the N-acetyl derivatives 7 in a chloroform/dimethyl sulfate mixture gives phthalocyanines 9 soluble in the pH range of 1 - 13. The electronic spectra of the phthalocyanines in buffered solutions (pH 4, 7, and 10) are examined. Furthermore, the electronic spectra of lutetium bis(phthalocyaninate) 9d in water and in DMSO are compared for the first time.

    Notes: Abstract D.c. conductivities of polycrystalline monoazacrown ether-substituted phthalocyanines (M=2H, Ni, Zn, Pb, Cu) and diphthalocyanine (M=Lu) are measured as Au-MPc-Au sandwiches to be of the order 10−10–10−12 S m−1. Chemical doping with oxidants (e.g. NOBF4) and enhancing the stacking of planar phthalocyanine moieties through the formation of alkali metal adducts with sodium and potassium ions leads to increase in conductivity of the order 101–102. The low conductivity and the diamagneticity of the bis(phthalocyaninato)-lutetium can be ascribed to the lack of radical nature in LuH(Pc)2. For the a.c. conductivities, lead and lutetium complexes form a group with higher conductivities and the rest show lower conductivity. The conduction activation energies calculated from Arrhenius plots exhibit the lowest value (0.40 eV) for the lutetium compound.

    Description / Table of Contents: Darstellung und Komplexbildung der Stereoisomeren von 1,3-Diphenyl-2-thioxo-4,5-bis-(hydroxyimino)-imidazolinDas neue α-Dioxim, 1,3-Diphenyl-2-thioxo-4,5-bis(hydroxyimino)-imidazolin, DTIH2, wurde synthetisiert. Anti- und amphi-Formen des DTIH2 konnten getrennt werden. Die anti- und amphi-Formen von CuII-, NiII-, CoII- und CoIII-Komplexen wurden isoliert, und es wurde versucht, ihre Strukturen anhand von IR, UV-VIS-Spektren und Elementaranalyse zu bestimmen. Die gegenseitige Umwandlung der anti- und amphi-NiII-Komplexe wurde untersucht.

The anti- and amphi-forms of CuII, NiII, CoII, and CoIII complexes have been isolated and their structures identified by using IR, UV-Visible and elemental analyses. The interconversion of anti- and amphi-NiII complexes has been studied.

    Notes: This paper provides a review of phthalocyan- ines suitable for the development of chemical sensors. Phthalocyanines may be utilized for different types of chemical sensors, including in particular electronic conductance sensors [such as semiconductive, field-effect transistor (FET), solid-state ionic and capacitance sensors], mass-sensitive sensors utilizing a quartz crystal microbalance (QCM) and surface acoustic-wave (SAW) sensors, and optical sensors. The phthalocyanines used are discussed in terms of their physical and chemical properties, as well as their sensitivity, selectivity and reversibility towards the detection of NO2 and organic solvent vapours. The interaction mechanism between phthalocyanine films and analyte molecules is also discussed.
