Abstract
A material with the empirical formula C3N3P is made by polymerizing P(CN)3 in a polar aprotic solvent such as acetonitrile, by heating, irradiation with ultraviolet light, and/or using a polymerization initiator and/or a catalyst.
Claims17
A method of making C3N3P, the method comprising:
- providing, in a sealable vessel, a solution of P(CN)3 in a polar aprotic solvent, and then
- heating the solution to at least 185° C. while the vessel is sealed, thereby obtain a polymer having the empirical formula C3N3P.
A method of making C3N3P, the method comprising:
- providing a starting solution of P(CN)3 in a polar aprotic solvent,
- irradiating the starting solution with ultraviolet light, thereby obtaining a dendrimeric prepolymer comprising C3N3P, and
- separating the prepolymer from the P(CN)3 and solvent.
