Abstract

This disclosure concerns two novel electrically conducting organic oligomers: oligo(3-amino-1H-pyrazole-4-carbonitrile) or “oligo(AP-CN)” and oligo(4-nitro-1H-pyrazole-3-yl-amine) or “oligo(AP-NO 2 )”, and methods of making thereof.

First claim

What we claim is:

1. A method of making an electrically conducting organic oligomer comprising:
preparing an acidic aqueous solution with a monomer;
preparing the acidic aqueous solution by mixing a solution of about 1.6 wt % HCl in DI water with a monomer (3-amino-1H-pyrazole-4-carbonitrile);
forming about a 0.3 M solution;
preparing a second aqueous solution with a sodium persulfate oxidant;
mixing the acidic aqueous solution with the second aqueous solution; and
allowing a reaction to proceed at about 40° C.

2. The method of making the electrically conducting organic oligomer of claim 1 further including the step of:
adding about 40 mg of monomer (3-amino-1H-pyrazole-4-carbonitrile) to about a milliliter of about 1.6 wt % HCl in DI water.

3. The method of making the electrically conducting organic oligomer of claim 1 further including the steps of:
preparing the second aqueous solution by adding ammonium persulfate (APS) to DI water; and
forming about a 0.44 M solution.

4. The method of making the electrically conducting organic oligomer of claim 2 further including the step of:
adding about 100 mg of APS to one milliliter of DI water.

5. The method of making the electrically conducting organic oligomer of claim 3 further including the steps of:
stirring vigorously for about 1 hour; and
converting about 15% of the monomer into polymer.
