Embodiment 1
[0050] From figure 1 It can be seen that the metal phthalocyanine complex (Phthalocyanine) has a planar macrocyclic molecule with a highly conjugated π-electron system.
[0051] (1) Weigh a certain amount of cobalt chloride (CoCl 2 ) (analytically pure), dissolved in hydrochloric acid to make solution one.
[0052] (2) Weigh a certain amount of phthalonitrile (analytical pure), and dissolve it in absolute ethanol, wherein the molar ratio of phthalonitrile and metal chloride salt is 4:1, and make solution 2.
[0053] (3) Slowly add solution 2 into solution 1 to form a mixed solution, and stir for 30 minutes.
[0054] (4) An appropriate amount of butyl titanate solution (analytically pure) is added to the above mixed solution, wherein the nominal molar ratio of the metal ion in the metal salt to the metal titanium in the butyl titanate is 1.0 mole percent).
[0055] (5) Hydrochloric acid (HCl) was added dropwise until the pH value of the above (4) solution was about 2.0.
