    Pyridine-Containing m-Phenylene Ethynylene Oligomers Having Tunable Basicities
    摘要:
    Incorporation of a pyridine monomer into the backbone of a m-phenylene ethynylene oligomer allows functionalization of the interior binding cavity of the folded oligomer. The basicity of the inwardly directed pyridine moiety was modulated by changing the substituents on the pyridine ring and through oligomer folding, granting access to a pK(a) range of 5-14 in acetonitrile.

    Single-Site Modifications and Their Effect on the Folding Stability of m-Phenylene Ethynylene Oligomers
    摘要:
    The folded structure of a m-phenylene ethynylene oligomer is tolerant to single-site modifications to both the backbone sequence and end groups. The helical structure is reinforced by multiple noncovalent interactions, allowing the oligomer sequence to be customized without a significant change in stability in most cases. The small changes that are observed are consistent with the expected behavior of pi-stacked systems and demonstrate subtle control over folding through single-site modifications.

  • Designing Structural Motifs for Clickamers: Exploiting the 1,2,3-Triazole Moiety to Generate Conformationally Restricted Molecular Architectures

    around the single bonds attached to both the 1‐ and 4‐positions of the 1,2,3‐triazole moiety and should therefore be able to induce well‐defined conformational preferences in higher oligomers and polymers, that is, foldamers. Various compounds were synthesized and characterized with regard to their preferred conformations in all three aggregation states—that is, in the gas phase, in solution as well
    限制在一个大分子中的非共价相互作用,尤其是氢键相互作用以及静电力,是设计在溶液中采用定义明确的构型的折叠剂的关键。在三唑连接的折叠剂(即所谓的Clickamers)领域近期的重要活动中,我们提出了一项基础研究,比较了带有相邻N-,O-或F-杂原子取代基的各种模型化合物。吸引和排斥相互作用的相互作用导致围绕连接于1,2,3-三唑部分的1和4位的单键周围的旋转约束,因此应能够在较高的低聚物中诱导明确定义的构象偏好和聚合物,即折叠剂。通过使用DFT计算,NMR光谱实验和X射线晶体学,合成并表征了所有化合物在所有三种聚集状态下(即气相,溶液中和固态)的优选构象,并对其进行了表征, 分别。根据对单个连接基序构象行为的一般理解,在不影响其独特折叠特性的情况下,由不同基序制备了异质结构。因此,这项工作提供了一种折叠架构造套件,该套件应能够设计出具有特定形状和所包含功能的各种Clickamer。NMR光谱

    The copper(i)-catalyzed azide–alkyne cycloaddition (CuAAC) reaction has been efficiently utilized to synthesize a series of dendrons with amino functionalities. The aminodendrons successfully underwent azodimerization to furnish a series of pyridyl- and phenyl-based azodendrimers with peripheral alkyl or ether side chain substituents. The molecular structures of the azodendrimers were fully assigned
