光诱导铜(I)催化多官能团叠氮化物和炔烃的聚合是通过乙酸铜(II)的光还原生成铜(I)离子而实现的，而不使用任何额外的光引发剂。聚合只能在溶液中进行，使用至少15wt%的甲醇。根据催化剂浓度的不同，可以实现定量的单体转化，从而可以确定机械性能。由叠氮化物和双炔组成的双功能体系的杨氏模量值最高，为1600 Mpa。
The photoinduced copper(I)-catalyzed polymerization of multifunctional azides and alkynes is facilitated by the photoreduction of copper(II) acetate generating copper(I) ions without using any additional photoinitiator. The polymerization can only be carried out in solution using at least 15 wt% of methanol. Depending on the catalyst concentration quantitative monomer conversions can be achieved allowing the determination of the mechanical properties. The bifunctional system consisting of a di-azide and di-alkyne exhibited the highest Young's modulus value of 1600 MPa.
