Synthesis and characterization 5,6-diaminouracils substituted metallo phthalocyanines

In this thesis study, new ball-type metallo phthalocyanines (MPc) 2',10',16',24'-tetrakis[4,4'-(5,6-diaminopyrimidine-2,4-diyl)bis(oxy)] diphthalocyanine dicobalt(II) 2, 2',10',16',24'-tetrakis[4,4'-(5,6-diaminopyrimidine-2,4-diyl)bis(oxy)] diphthalocyanine dizinc(II) 3 and 2',10',16',24'-tetrakis[4,4'-(5,6-diaminopyrimidine-2,4-diyl)bis(oxy)] diphthalocyanine lutetium(III) 4 have been synthesized in two steps. In the first step, 4,4'-[(5,6-diaminopyrimidine-2,4-diyl)bis(oxy)]dibenzene-1,2-dicarbonitrile 1 which is the starting key molecule of the ball-type Pcs was obtained from 4-nitrophthalonitrile and 5,6-diaminouracil sulfate with K2CO3 in DMF at 70 ºC. In the second step, the new ball-type metallo phthalocyanines with four uracil groups on the periphery were prepared by the reaction of 4,4'- [(5,6-diaminopyrimidine-2,4-diyl)bis(oxy)]dibenzene-1,2-dicarbonitrile 1 and the corresponding metal salts (Co(OAc)2.4H2O, Zn(OAc)2.2H2O and Lu(OAc)3.H2O) in the medium without solvent. In the synthesis of new ball-type metallo phthalocyanines (Co2Pc2, Zn2Pc2 and LuPc2) were used 'heating of the solid phase method'. The structure of the synthesized compounds were characterized using FT-IR; UV-Vis; H-NMR and MALDI-TOF mass spectroscopy techniques. Key Works : Phthalocyanine, Cobalt, Zinc, Lutetium
