A method for preparing a catalyst, the method comprising:
- heating a reaction mixture comprising a transition metal compound, a perfluoroalkyl phenol, and an alkyne in a reaction vessel;
- and
- removing the alkyne by purging with an inert gas.
A method of preparing a polydiacetylene, the method comprising:
- providing at least one enediyne substrate and at least one catalyst;
- and
- performing a metathesis reaction with the at least one enediyne substrate and the at least one catalyst in a reaction vessel to produce the polydiacetylenes.
A composition comprising:
- at least one catalyst and one or more of the following:
- at least one enediyne substrate or at least one polydiacetylene product,
- wherein the at least one catalyst is represented by the formula
- where M is molybdenum or tungsten;
- R1, R2 and R3 are, independently, a perfluoroalkyl group represented by the formula —(CF2)nF;
- n is an integer from 2 to 24;
- and
- R4 is an alkyl or a heteroalkyl group.
