Synthesis of nitrogen-containing polymers has always been a hot research topic for their broad applications as functional materials. In this work, we established new, spontaneous, and atom-economic amino-yne dick polymerization for the construction of regio-/stereoregular nitrogencontaining polymers. Aroylacetylenes, which could be facilely prepared without using water-sensitive ethynylmagnesium bromide and harsh reaction conditions, could be polymerized with amines in the absence of any catalyst under ambient conditions, and poly(beta-enaminone)s with high weight-average molecular weights (M-w, of up to 49 400) could be produced in excellent yields (up to 99%). Moreover, sole E-isomer-containing polymers could be obtained efficiently from the click polymerization of aroylacetylenes and secondary amines, whereas absolute Z-configuration products were prepared when using primary amines. In addition, poly(beta-enaminone)s could be degraded upon the addition of Lewis acid and primary amines in aqueous solution and definite compounds could be generated, proving their wide application prospects as degradable nitrogen-containing polymers.
