Multicomponent polymerizations (MCPs) have emerged as a powerful tool in the synthesis of advanced, sequence-regulated polymers based on their mild reaction conditions, ease of use, and high atom economy. Herein, we exploit MCP methodology to introduce elemental selenium into a polymer chain, accessing a unique polymer class,i.e., polyselenoureas. These polyselenoureas can be synthesized from a broad range of commercially available starting materials, in a simple ambient temperature one-step procedure. The incorporation of selenium directly into the polymer backbone provides a unique handle for polymer characterization based on the distinctive isotope profiles exposed by high-resolution mass spectrometry, along with diagnostic signals observed in infrared and X-ray photoelectron spectroscopies. In addition, diffusion ordered spectroscopy provides access to hydrodynamic diameter information on the generated unique polymer class.

以元素硒为单体的多组分聚合聚硒脲

基于其温和的反应条件、易用性和高原子经济性，多组分聚合 (MCP) 已成为合成先进的序列调节聚合物的有力工具。在此，我们利用 MCP 方法将元素硒引入聚合物链中，从而获得一种独特的聚合物类别，即聚硒脲。这些聚硒脲可以由多种市售起始材料通过简单的环境温度一步法合成。将硒直接掺入聚合物主链为聚合物表征提供了独特的方法，该方法基于高分辨率质谱法暴露的独特同位素分布，以及在红外和 X 射线光电子能谱中观察到的诊断信号。此外，
