These N-H groups are also observed by stretching vibrations at 3280 cm“1 in the IR spectrum. Electronic spectrum can be used efficiently in order to differentiate metal-free and metalloporphyrazines. While Q band absorptions are splitted into two peaks around 600-700 nm in the first, the same absorptions appear as a single peak in the latter. So the single intense peak at 672 nm for MgPza is splitted into two relative weak peaks at 638 nm and 709 nm. The reason for the splitting is the change of symmetry from D4h to D2h- In order to incorporate different metal ions into the porphyrazine core, IfoPza is the starting point while the inner core protons can be exchanged with metal ions. CoPza was obtained from H2Pza and Co-acetate by refluxing in ethanol. IR spectrum of CoPza is very similar to MgPza and there is a single Q band absorption (Table 3). B band absorption is at 326 nm. XVUlTable 3. Electronic spectral data for MPza derivatives. In conclusion, we have accomplished to synthesize two different types of porphyrazine. The one with l,3-dithiol-2-thione ring on the periphery is not soluble in common organic solvents and can be considered two have similarities with phthalocyanine structure. The second group with eight dimethylaminoethyl substituents is soluble and also quaternarizable with alkyl halides.
