Li, Baixue; Liu, Yong; Nie, Han; Qin, Anjun; Tang, Ben Zhong published the artcile< Phosphazene Base-Mediated Azide-Alkyne Click Polymerization toward 1,5-Regioregular Polytriazoles>, Safety of 1,2-Bis(4-bromophenyl)-1,2-diphenylethene, the main research area is phosphazene base azide alkyne click polymerization regioregular polytriazole.

Cu(I)-catalyzed azide-alkyne click polymerization has become a powerful tool for the construction of 1,4-regioregular polytriazoles (PTAs). However, the polymerization toward the synthesis of 1,5-regioregular PTAs has been rarely reported, and the structure-property relationship between 1,5- and 1,4-regioregular PTAs needs to be studied further. In this work, an efficient superbase of phosphazene base (t-BuP4)-mediated azide-alkyne click polymerization was developed, and soluble and thermally stable 1,5-regioregular PTAs with high mol. weights (Mw up to 26 600) were generated in high yields (up to 99%). The relationship between the regiostructures and the thermal stability, light refractivity, photophys. properties, electrochem. behaviors of PTAs was investigated, and the results indicate that the 1,4-regioregular PTA exhibits better conjugation and planarity than that of the 1,5-regioregular one. Thus, this work not only develops a powerful t-BuP4-mediated azide-alkyne click polymerization for the preparation of 1,5-regioregular PTAs but also provides a platform for investigating the structure-property relationship of PTAs, which will guide the design of new PTAs for diverse applications.
