The development of a germanium-based linker system for the solid phase synthesis (SPS) of 3-(n-hexyl)thiophene oligomers and the first SPS of triarylamine oligomers via iterative chain extension is described. The efficiency of the key steps in the oligomer syntheses and their compatibility with the germanium linker are demonstrated by the SPS of bi-[3-(n-hexyl)thiophene] 19 and ter-(triarylamine) 50
描述了一种基于锗的接头系统的开发,该系统用于通过迭代扩链进行3-(n-己基)噻吩低聚物和三芳基胺低聚物的第一个SPS的固相合成(SPS)。低聚合成中关键步骤的效率及其与锗连接基的相容性通过联[3-(正己基)噻吩] 19和叔-(三芳基胺)50的SPS进行了证明。适当地选择的基于硅的封闭/保护基的结合基团允许双重偶联以驱动关键的交叉偶联步骤完成,因此使缺失序列最小化,并且还允许从树脂无痕和潜在的功能性裂解。
