    定量控制供体-受体 [2] 假轮烷中三级结构的 π-π 相互作用
    摘要:
    依赖于 π-供体-受体亚基之间相互作用的假轮烷和互锁分子的灵活性提供了对让人联想到蛋白质三级结构的折叠结构的访问。虽然它们之前已经被描述过,但直到现在我们才能够通过使用专为此目的设计的假轮烷来量化一种这样的三级结构。在这里,折叠结构内假轮烷的增强稳定性被测量为 ΔG = ca。0.5 kcal mol(-1)。三级结构通过四硫富瓦烯基 π 供体之间的电荷转移相互作用而稳定,该供体可以通过折叠柔性接头与接受 π 的百草枯基大环并列。在室温下,估计这里检查的 70% 的假轮烷以其折叠状态存在。

    molecular electronics. Protocols enabling the synthesis of functionalised MPTTFs and BPTTFs are therefore of broad interest. Herein, we present the synthesis of a range of functionalised MPTTF and BPTTF species. Firstly, the large-scale preparation of the precursor species N-tosyl-(1,3)-dithiolo[4,5-c]pyrrole-2-one (6) is described, as well as the synthesis of the analogue N-tosyl-4,6-dimethyl-(1,3)-dithiolo[4
    四硫富瓦烯(TTF,1)部分的电子给体和独特的氧化还原特性已导致在许多化学领域中的各种应用。单吡咯并四硫富瓦烯(MPTTF,4)和双吡咯并四硫富瓦烯(BPTTF,5)是有用的结构基序,并已在超分子化学和分子电子学等领域得到广泛使用。因此,能够合成功能化的MPTTF和BPTTF的协议引起了广泛的关注。在这里,我们介绍了一系列功能化的MPTTF和BPTTF种类的合成。首先,描述了前体物质N-甲苯磺酰基-(1,3)-二硫代[4,5-c]吡咯-2-酮(6)的大规模制备以及类似物N-的合成甲苯磺酰基-4,6-二甲基-(1,3)-二硫代[4,5-c]吡咯-2-酮(7)。之后,我们展示了6和7如何通过均相偶联反应和功能化的MPTTF与多种1,3-二硫代-2-硫酮的交叉偶联反应来制备BPTTF(19)。随后,讨论了更复杂功能的合并。我们展示了如何使用2-氰基乙基保护基来提供被硫醚官能化的MPTTF,例如一系列乙二醇衍生物。此外,还讨论了1
  • Evidence of Strong Hydration and Significant Tilt of Amphiphilic [2]Rotaxane Molecules in Langmuir Films Studied by Synchrotron X-ray Reflectivity

    Surface sensitive X-ray techniques have been used to elucidate the structures of amphiphilic [2]rotaxane and dumbbell monolayers at the air/water interface. The [2]rotaxanes were found to adopt highly hydrated tilted and/or folded conformations on the water surface largely due to the hydrophilic nature of their tetracationic ring component. This conformation was less pronounced in monolayers of the dumbbell precursors. Increasing the surface pressure resulted in an expansion of [2]rotaxane monolayers in the vertical direction and decreased hydration.
  • Mechanistic Evaluation of Motion in Redox-Driven Rotaxanes Reveals Longer Linkers Hasten Forward Escapes and Hinder Backward Translations

    Mechanistic understanding of the translational movements in molecular switches is essential for designing machine-like prototypes capable of following set pathways of motion. To this end, we demonstrated that increasing the station-to-station distance will speed up the linear movements forward and slow down the movements backward in a homologous series of bistable rotaxanes. Four redox-active rotaxanes, which drove a cyclobis(paraquat-p-phenylene) (CBPQT(4+)) mobile ring between a tetrathiafulvalene (TTF) station and an oxyphenylene station, were synthesized with only variations to the lengths of the glycol linker connecting the two stations (n = 5, 8, 11, and 23 atoms). We undertook the first mechanistic study of the full cycle of motion in this class of molecular switch using cyclic voltammetry. The kinetics parameters (k, Delta G(double dagger) of switching were determined at different temperatures to provide activation enthalpies (Delta H-double dagger) and entropies (Delta S-double dagger). Longer glycol linkers led to modest increases in the forward escape (t(1/2) = 60 to <7 ms). The rate-limiting step involves movement of the tetracationic CBPQT(4+) ring away from the singly oxidized TTF+ unit by overcoming one of the thiomethyl (SMe) speed bumps before proceeding on to the secondary oxyphenylene station. Upon reduction, however, the return translational movement of the CBPQT(4+) ring from the oxyphenylene station back to the neutral TTF station was slowed considerably by the longer linkers (t(1/2) = 1.4 to >69 s); though not because of a diffusive walk. The reduced rate of motion backward depended on folded structures that were only present with longer linkers.
