Hypothesis
Can cationic glycidyl triazolyl polymers be synthesized without copper catalysts while maintaining high ionic conductivity?
Conclusion
The study successfully synthesized cationic glycidyl triazolyl polymers without copper catalysts, achieving high ionic conductivity, particularly with the N-EG3 substituent.
Supporting Evidence
- The ionic conductivity of GTP-N-EG3·TFSI reached 6.8 × 10−6 S cm−1 at 25 °C under dry conditions.
- Microwave-assisted reactions significantly reduced the time required for decarboxylation.
- The study revisited and refined the synthetic procedure originally reported by H. L. Cohen in 1981.
Takeaway
Scientists found a way to make special polymers that conduct electricity without using copper, which makes the process easier and the materials better at conducting.
Methodology
The polymers were synthesized through thermal azide-alkyne cycloaddition, followed by decarboxylation and quaternization of the triazole unit.
Limitations
The study did not measure the molecular weights of GTP-COOH and cationic GTPs by SEC due to adsorption issues.
