Sythesis, Structure And Characteristic Of Three Metal (Ⅱ) Substituted Phthalocyanines

The phthalocyanine itself is a 18-л conjugated system, when this system is extended the modified phthalocyanine often have special structural and functional characterizations.The applications of phthalocyanine are concerning catalyse ,sterilization ,molecule material apparatus, photo-recordm materials and xerography. We are supposed to synthesize purified substituted phthalocyanines. The complexes of hexadecachloro--phthalocyanine, octacarboxylic acid--phthalocyanine, quinoline-phthalocyanine with metal were prepared. The structures of these compounds were studied by MS, IR and UV-Vis absorption spectra. From the Mass Spectroscopy, every substituted phthalocyanine have its molecule-ion peak accordingly. But the content and purity were low. From the UV-Vis absorption spectra,there are two bands:Q-band and B-band. The conjugated system in phthalocyanine made Q-band and B-band red-shift. The phthalocyanines we get have the same characterization as those extended conjugated system: one of the peculiar asorption of Pc the Q band is einstein shift, the other Soret band broadens. Metal phthalocyanine derivatives are insoluble in most commom organic solvents, difficulty in purification so that it is hard to synthesis the functional materials.
