Synthesis and Characterization of New D-pi-D Type Schiff Base Ligands

Keser Karaoglan G., Erden I., Avciata U.

Polish Journal of Chemistry

2009

Vol. 83, nr 6

1147-1152

Two new Schiff bases with D-pi-D type have been success fully synthesized using the reaction of 3,3'-dimethylnapthide and 3,3',5,5'-tetramethylbenzidine with 4-(dimethyl - amino)cinnamaldehyde. The Schiff base ligands L1 and L2 have been characterized by IR, UV-vis i ble, 1H NMR and fluorescence spectra, as well as TGA-DSC-DTG, elemental analyses and mass spectra.

Synthesis, Characterization and Electrochemistry of New Type Soluble Porphyrazine Containing 3-Phenylpropylthio Substituent

Erdogmus A., Koca A., Avciata U., Gül A.

Polish Journal of Chemistry

2008

Vol. 82, nr 8

1541-1541

Octakis(3-phenylpropylthio) porphyrazines MPz(SR)8, where (M = Mg, H, Ni, Zn, Co) and R = C9H11, were synthesized starting with the corresponding unsaturated dicarbonitrile derivative. These new compounds have been investigated and characterized by UV, FT-IR, 1H NMR, GC-MS and elemental analysis methods. As in the case of the unmetalated species, [H2Pz], three reversible one-electron reductions and one reversible oxidation process (two for Co(II)Pz) were observed for all of the metal complexes. The E1/2 values are similar for the H2Pz, Ni(II)Pz and Zn(II)Pz derivatives with negative shift due to the different effective charges of the central metal ion. Peak to peak separations and separation between the first reduction and first oxidation couples related with the HOMO-LUMO gap of the complexes are in harmony with the common porphyrazine complexes.
