17,18-Dibromo-8-methyl-4,12-ditosyl-3,4,5,6,7,8,9,10,11,12,13,14-dodeca­hydro-2H-benzo[b][1,4,7,11,15]dioxatriaza­cyclo­hepta­decine

In the title compound, C31H39Br2N3O6S2, a 17-membered aza-macrocyclic ligand containing two ether O and three aza N atoms, the three pendant aromatic rings form an ‘E’ shape. The dihedral angles between the central benzene ring and the side ones are 17.8 (3) and 7.4 (3)°, and the dihedral angle between the tosyl rings is 10.6 (3)°. The methyl group is disordered over two orientations, with occupancies of 0.52 (15) and 0.48 (15)

4-[2-(Cyclo­hexa-1,4-dien-1-yl)eth­oxy]benzene-1,2-dicarbonitrile

In the title compound, C16H14N2O, the dihedral angle between the aromatic rings is 70.23 (6)°. The linking chain has a zigzag conformation. In the crystal, mol­ecules are linked by weak inter­molecular C—H⋯N hydrogen bonds, forming a zigzag chain along the c axis

The synthesis and characterization of a porphyrazine bearing aza-15-crown-5 moieties in the peripheral positions and its cobalt(II) complex

Biyiklioglu, Zekeriya/0000-0001-5138-214XWOS: 000253205200007The synthesis of novel metal-free (H-2-Pz) and metalloporphyrazines (MgPz and CoPz), peripherally substituted with eight aza-15-crown-5 moieties, is described. The novel compounds were characterized by elemental analysis, i.r, H-1 and C-13-n.m.r, UV-vis and m.s. spectral data

Synthesis, characterization and investigation of electrochemical and spectroelectrochemical properties of peripherally tetra 4-phenylthiazole-2-thiol substituted metal-free, zinc(II), copper(II) and cobalt(II) phthalocyanines

AKCAY, Hakki Turker/0000-0002-8502-9608; KOCA, ATIF/0000-0003-0141-5817;WOS: 000401593400074In this study novel peripherally tetra 4-phenylthiazole-2-thiol substituted metal-free phthalocyanine (4) and its zinc(II) (5), copper(II) (6) and cobalt(II) (7) derivatives were synthesized and characterized by a combination of various spectroscopic techniques such as FT-IR, H-1-NMR, UV-vis and MALDI-TOF mass. Electrochemical characterizations of metallo-phthalocyanine complexes were conducted by voltammetric and in situ spectroelectrochemical measurements. (CoPc)-Pc-II went [(CoPc-2)-Pc-II]/[(CoPc-2)-Pc-I](1-), [(CoPc-2)-Pc-I](1-)/ [(CoPc-3)-Pc-I](2-), [(CoPc-3)-Pc-I](2-)/[(CoPc-4)-Pc-I](3-) and [(CoPc-2)-Pc-I]/[(CoPc-2)-Pc-II](1+) reduction and oxidation processes respectively. Differently (ZnPc)-Pc-II only showed four ligand-based reductions and two ligand based oxidation processes. (C) 2017 Elsevier B.V. All rights reserved

Synthesis, characterization and electrochemistry of a new organosoluble metal-free and metallophthalocyanines

Biyiklioglu, Zekeriya/0000-0001-5138-214X; TOPCU, Saim/0000-0002-1169-6037WOS: 0002557210000194 -[2-(Phenylthio)ethoxy]phthalonitrile 3 was synthesized by nucleophilic displacement of nitro group in 4-nitrophthalonitrile with 2-(phenylthio)ethanol 1. The metal-free phthalocyanine 4 was prepared by the reaction of a dinitrile monomer with 2-(dimethylamino)ethanol. Ni(II), Co(II), Cu(I) phthalocyanines 5, 7, 8 were prepared by reaction of the dinitrile compound with the chlorides of Ni(II), Co(II), Cu(I) in DMAE. Zn(II) phthalocyanine 6, was prepared by reaction of the dinitrile compound with the acetates of Zn(II) in DMAE. Electrochemical behaviours of novel metal-free, Co(II) and Zn(II) phthalocyanines were investigated by cyclic voltammetry, potential differential pulse voltammetry techniques. The new compounds were characterized by a combination of IR, (1)H NMR, (13)C NMR, UV-Vis, elemental analysis and MS spectral data. (C) 2008 Elsevier Ltd. All rights reserved
