Özet
The synthesis of novel zinc and cobalt metallo phthalocyanines with four 7-oxy-3-(4-pyridyl)coumarin dye groups on the periphery/non-periphery were prepared by cyclotetramerization of 7-(3,4-dicyanophenoxy)-3-(4-pyridyl)coumarin (1)/7-(2,3-dicyanophenoxy)-3-(4-pyridyl)coumarin (2) and also a phthalocyanine based on supramolecular structures have been prepared by the ready coordination of pyridine donor sites in 2,9(10),16(17),23(24)-tetrakis[7-oxo-3-(4-pyridyl) coumarin]-phthalocyaninatozinc (1a)/1,8(11),15(18),22(25)-tetrakis[7-oxo-3-(4- pyridyl)coumarin]-phthalocyaninatozinc (2a) with vanadyl bis(acetylacetonate). The novel chromogenic compounds were characterized by elemental analysis, 1H NMR, Mass spectra, FT-IR and UV-Vis spectral data. The IR-spectra of prepared compounds showed two characteristic intense bands at 1728-1719 cm -1 for lactone carbonyl and at 1592 cm -1 for the α, β unsaturated doubled bond. © 2012 Elsevier Ltd.
