  Helical Molecular Programming: Supramolecular Double Helices by Dimerization of Helical Oligopyridine-dicarboxamide Strands

  摘要：

  Helically preorganized oligopyridine-dicarboxamide strands are found to undergo dimerization into double helical supramolecular architectures. Dimerization of single helical strands with five or seven pyridine rings has been characterized by NMR and mass spectrometry in various solvent/ temperature conditions. Solution studies and stochastic dynamic simulations consistently show an increasing duplex stability with increasing strand length. The double helical structures of three different dimers was characterized in the solid phase by X-ray diffraction analysis. Both aromatic stacking and hydrogen bonding contribute the double helical arrangement of the oligopyridine-dicarboxamide strand. Inter-strand interactions involve extensive face-to-face overlap between aromatic rings, which is not possible in the single helical monomers. Most hydrogen bonds occur within each strand of the duplex and stabilize its helical shape. Some inter-strand hydrogen bonds are found in the crystal structures. Dynamic studies by NMR as well as by molecular modeling computations yield structural and kinetic information on the double helices and on monomer-dimer interconversion. In addition, they reveal the presence of a spring-like extension/compression as well as rotational displacement motions.

  螺旋分子编程：将寡吡啶-二甲酰胺折叠成分子单个螺旋。

  摘要：

  由交替的2，6-二氨基吡啶和2，6-吡啶二羰基单元组成的分子链已被设计成在形成分子内氢键时自组织成单链螺旋结构。五聚体链11、12和14，七聚体链1和20以及非十聚体链15已经使用逐步收敛策略合成。通过对这些化合物中的四种进行单晶X射线衍射分析，已表征了固态的单螺旋构象。来自五聚体链12和14的螺旋延伸一圈，来自七聚体20和非十聚体15种的螺旋分别延伸一圈半和二圈半。分子内氢键负责股线的强烈弯曲。极性和非极性有机溶剂中的1 H NMR位移均表明外围芳族基团之间存在分子内重叠。因此，螺旋构象在溶液中也占主导地位。从高能延伸线性构象异构体开始的链折叠的分子随机动力学模拟显示，快速（在300 K时为600 ps）转变为稳定的螺旋构象。
