Abstract

Described herein is the preparation of carbon phosphonitride pre-polymers that are soluble in organic solvents and can be further thermoset into carbon phosphonitride extended solids (i.e. films, monoliths, etc.) with an approximate empirical formula of C 3 N 3 P.

Claims (9)

1. A method of preparing a pre-polymer, the method comprising:

reacting potassium cyanide with phosphorus trichloride in a polar aprotic solvent, thereby obtaining a pre-polymer consisting essentially of phosphorus, carbon, and nitrogen.

2. The method of claim 1 , wherein the solvent is acetonitrile.

3. A method of preparing a pre-polymer, the method comprising:

reacting silver cyanide with phosphorus trichloride in a polar aprotic solvent, thereby obtaining a pre-polymer comprising phosphorus, carbon, and nitrogen.

4. The method of claim 3 , wherein the solvent is acetonitrile.

5. The method of claim 3 , further comprising the inclusion of a metal nitrate in the reaction of the silver cyanide with phosphorus trichloride.

6. The method of claim 5 , wherein the metal nitrate is silver nitrate.

7. The method of claim 5 , wherein the solvent is acetonitrile.
