[0045] Secondly, the present invention discloses a preparation method of azo-substituted phthalocyanine covalent polymer nanomaterial AzoCoPc-CMPs, which includes the following steps:
[0046] (1) adding tetranitrophthalocyanine cobalt and tetraaminophthalocyanine cobalt to an organic solvent for dissolution, and preparing a phthalocyanine mixed solution under alkaline conditions;
[0047] (2) heating and stirring the solution of step (1) to react;
[0048] (3) The mixture obtained in step (2) is centrifuged at high speed, and the obtained solid is washed with an organic solvent, activated and then dried to obtain the final nanomaterial.
[0049] As a further technical solution, in step (1), the organic solvent is N,N dimethylformamide (DMF), and the concentration of the reactant in step (1) is 0.9mmol L -1 .
[0050] As a further technical scheme, in step (1), the alkali is potassium hydroxide, and the concentration of substance of potassium hydroxide in step (1) is 9mmol L ...

[0057] 1. Preparation of azo-substituted cobalt phthalocyanine organic porous nanopolymers (AzoCoPc-POPs):
[0058] Weigh 0.68g tetranitrocobalt phthalocyanine (TN-CoPc), 0.57g tetraaminocobalt phthalocyanine (TA-CoPc) and 0.50g potassium hydroxide into a 100mL three-neck flask, add 50mL dry N,N-dimethyl Dimethyl formamide (DMF) as solvent, in N 2 Under protection, the reaction temperature was 160° C., and the reaction was stirred for 48 hours. Cool to room temperature, add to excess saturated saline and stir, let stand for 12 hours and then filter. The resulting solid is ultrasonically washed with a large amount of distilled water, DMF, absolute ethanol, etc., and then centrifuged to obtain a solid. Dry at 80°C to obtain dark green solid, azo-substituted cobalt phthalocyanine organic porous nanopolymers (AzoCoPc-POPs).

[0066] Preparation of azo-substituted cobalt phthalocyanine organic porous polymers (AzoCoPc-POPs):
[0067] Weigh 0.68g tetranitrocobalt phthalocyanine (TN-CoPc), 0.57g tetraaminocobalt phthalocyanine (TA-CoPc) and 0.50g potassium hydroxide into a 100mL three-neck flask, add 50mL dry N,N-dimethyl Dimethyl formamide (DMF) as solvent, in N 2 Under protection, the reaction temperature was 160° C., and the reaction was stirred for 36 hours. Cool to room temperature, add to excess saturated saline and stir, let stand for 12 hours and then filter. The resulting solid is ultrasonically washed with a large amount of distilled water, DMF, absolute ethanol, etc., and then centrifuged to obtain a solid. Drying at 80°C yielded a dark green solid.
[0068] The preparation of the AzoCoPc-POPs electrode is the same as in Example 1.
