Here we report the first synthesis of sequence-defined polytriazoles, in which different side groups are sequentially anchored to the C-5 position of 1,2,3-triazole rings. By using efficient synthetic strategies based on IrAAC and CuAAC, different monodispersed polytriazoles with up to ∼5.3 kDa and 31-mer were constructed. Structural characterization via NMR, SEC, MALDI-TOF-MS, tandem MS and FTICR-MS
在这里,我们报道了序列定义的聚三唑的首次合成,其中不同的侧基顺序锚定在1,2,3-三唑环的C-5位置。通过使用基于IrAAC和CuAAC的有效合成策略,构建了高达〜5.3 kDa和31-mer的不同单分散聚三唑。结构表征通过NMR,SEC,MALDI-TOF-MS,串联MS和FTICR-MS证实具有期望指定序列和详细的链长度polytriazoles的形成。
