Aroylacetylene Based Amino-Yne Click Polymerization toward Nitrogen Containing Polymers

A highly efficient, spontaneous, and atom-economic polymerization of aroylacetylenes and amines at room temperature in air was established, and poly(<i>β</i>-enaminone)s with high molecular weights were produced in nearly quantitative yields. Moreover, singly <i>E</i>-configuration polymers can be obtained efficiently with secondary amines, while absolute <i>Z</i>-configuration products were prepared when using primary amines. In addition, the poly(<i>β</i>-enaminone)s can be degraded by primary amines in aqueous system to obtain definite compounds, proving their wide application prospects as degradable nitrogen containing polymers.
