The Cu I -catalyzed, but ligand-free azide-alkyne cycloaddition reaction was applied to the polymerization of the newly synthesized diethynyl-functionalized 2-pyrone monomer originally isolated from lignin via metabolic pathway. The polymerization was monitored by GPC and IR spectra and the resulting high molecular weight polymer was unambiguously characterized by 1 H NMR, thermal analysis, and optical
将 Cu I 催化但无配体的叠氮化物-炔环加成反应应用于新合成的二乙炔官能化 2-吡喃酮单体的聚合反应,该单体最初是通过代谢途径从木质素中分离出来的。聚合反应通过 GPC 和 IR 光谱监测,所得高分子量聚合物通过 1 H NMR、热分析和光吸收和发射光谱明确表征。
