of oligomeric strands. We have designed an aromatic amide foldamer in which each monomer encodes three levels of information: a specific cavity size, recognition groups for guest binding, and a propensity to adopt a single or a double helical motif. Thus, a tetradecameric sequence based on four different monomers was encoded so that a wide double helical segment resulting from the hybridization of
在本手稿中,我们介绍了一种基于新设计的超分子胶囊,该胶囊既依赖于寡聚体链的自组装又可以折叠。我们设计了一种芳族酰胺折叠剂,其中每个单体编码三个信息级别:特定的空腔尺寸,用于客体结合的识别基团和采用单个或双螺旋图案的倾向。因此,编码了基于四种不同单体的十四聚体序列,因此,由两条链的杂交产生的宽双螺旋片段产生了一个空腔,在该空腔中可以结合来宾(例如1,10-癸二醇)。另外,两个狭窄的单螺旋段形成端盖,并将客体与溶剂隔离。介绍了双链体形成和客体结合的设计,合成,固态和溶液状态表征。
