Özet

Novel polymeric metal-free and metallo(Cu(II), Co(II), Ni(II), Zn(II) and Pb(II))-phthalocyanine complexes were synthesized using microwave irradiation and the products were purified by several (crystallization and preparative thin layer) techniques. The newly prepared compounds were characterized by a combination of elemental analyses, IR, H-1/C-13 NMR,H-1-H-1 COSY, MS and UV-Vis spectroscopy. In order to better understand the spectroscopy data (especially for H-1/C-13 NMR and H-1-H-1 COSY techniques), computational calculations were used for characterization at DFT/6-31G(d) level. The electronic spectra exhibited an intense pi -> pi* transition with characteristic Q and B bands of the phthalocyanine core. (C) 2009 Elsevier Ltd. All rights reserved.
