organogels are formed by the furanoside but not the pyranoside. The influences of the sugars are also displayed by the different shaped superstructures of the free nucleosides in solution. The readout of the information in the base moiety is therefore tailored by the sugar configuration, and the interplays exert subtle effects on the structures, from solid to gel and to the solution state. The potential
结构修饰的核苷是核酸化学领域的核心角色。首次合成了腺嘌呤-胸腺嘧啶(AT)嘧啶[4,5-d]嘧啶呋喃糖基和吡喃糖基阿拉伯核苷。单晶X射线衍射分析揭示了新颖的碱基对,它们与糖残基协同作用,指导包含通道和腔的独特网络的出现。微观的非共价连接可以转化为宏观水平,其中呋喃糖苷而不是吡喃糖苷形成坚固的有机凝胶。溶液中游离核苷的不同形状的超结构也显示了糖的影响。因此,通过糖的构型调整碱基部分中信息的读出,相互作用对结构产生微妙的影响,从固体到凝胶再到溶液状态。形成这些吸引人的碱基对和更高结构的潜力使这些引人入胜的核苷可以在各个领域中充当独特的构建基块或构建创新的核酸结构。
