Claims10
A method of forming a monomer:
- comprising, the reaction:
- in the presence of a base which is potassium tert-butoxide in a single reaction vessel at room temperature and a reaction time of 30 minutes to achieve a yield of at least 95% with quantitative conversion, wherein X is a halo atom selected from the group consisting of Cl, Br and I.
A method of forming a polymer, comprising:
- forming exomethylene functionalized 3,4-ethylenedioxythiophene monomer having the formula:
- via the reaction:
- in the presence of a base which is potassium tert-butoxide in a single reaction vessel at room temperature and a reaction time of 30 minutes to achieve a yield of at least 95% with quantitative conversion, wherein X is a halo atom selected from the group consisting of Cl, Br and I;
- and
- polymerizing monomers comprising at least one of the exomethylene functionalized 3,4-ethylenedioxythiophene monomer or a reaction product of the exomethylene functionalized 3,4-ethylenedioxythiophene monomer and a compound including a group reactive with the exomethylene group of the exomethylene functionalized 3,4-ethylenedioxythiophene monomer via a polymerization reaction, wherein the monomers have a purity of at least 95% in the polymerization reaction.
