  使用点击化学有效模板合成供体-受体轮烷

  摘要：

  有机叠氮化物和末端炔烃之间的 Cu 催化的 Huisgen 1,3-偶极环加成（“点击化学”）的温和反应条件、显着的官能团相容性和完全的区域选择性导致了一种先穿后塞的方法合成包含环双（百草枯-对亚苯基）（CBPQT4+）作为π-受体环组分的供体-受体轮烷。轮烷的形成是通过使含有 pi 供体 1,5-二氧萘 (DNP) 识别单元的叠氮化物官能化假轮烷与适当的炔官能化终止剂反应而引发的。在这种有效的、动力学控制的组装后共价修饰中获得的高产率以及合成方案的出色收敛性通过 [2]-、[3]-、

  Self-Assembly, Spectroscopic, and Electrochemical Properties of [n]Rotaxanes¹

  摘要：

  Synthetic approaches to self-assembling [n]rotaxanes incorporating pi-eleclron deficient bipyridinium-based dumbbell-shaped components and pi-electron rich hydroquinone-based macrocycles have been developed. In particular, the so-called slippage methodology relies upon the size complementarity of preformed macrocyclic and dumbbell-shaped components. The spontaneous self-assembly of these complementary components into a rotaxane in solution can be achieved under the influence of an appropriate amount of thermal energy. The absorption spectra, luminescence properties, and electrochemical behavior of the rotaxanes and their dumbbell-shaped components have been investigated and discussed on the basis of the behavior of their chromophoric and electroactive units. Charge-transfer and energy-transfer processes between specific chromophoric subunits and unusual correlations between the redox patterns of the various compounds have been evidenced and interpreted.

  and the CBPQT4+ ring in the [2]rotaxanes. Thus, the CBPQT4+ rings in the degenerate [2]rotaxanes exhibit slow shuttling between two DNP recognition sites on the 1H NMR time-scale on account of the electrostatic barrier posed by the bispyridinium units, as demonstrated by variable-temperature 1H NMR spectroscopy. Electrochemical experiments carried out on the [2]rotaxanes 1·6PF6 and 2·6PF6 indicate that

• Switchable Neutral Bistable Rotaxanes

  Two switchable neutral bistable [2]rotaxanes have been synthesized, and their chemically induced mechanical switching has been studied in solution by 1H NMR spectroscopy. One of the rotaxanes was prepared by a thermodynamically controlled slippage mechanism, while the other rotaxane was obtained by a dynamic covalent chemistry protocol involving the assembly of its dumbbell component by olefin metathesis. The recognition sites present in the rod section of the dumbbell component, namely, naphthodiimide (NpI) and pyromellitic diimide (PmI) residues, were chosen in the knowledge that the ring component, 1,5-dinaphtho[38]crown-10 (1/5DNP38C10), will bind preferentially to the NpI site. However, upon introduction of Li+ ions into the solution, a 1:2 complex is formed between the PmI site, encircled by the 1/5DNP38C10 ring and two Li+ ions. Since this complex is more stable overall than the binding between the 1/5DNP38C10 ring and the NpI site, the ring component moves from the NpI site to the PmI one. This mechanical movement can be reversed by adding an excess of [12]crown-4 to the solution to act as a sequestering agent for the Li+ ions.

  Two [2]rotaxanes and a [2]pseudorotaxane containing 1,5-dioxynaphthalene recognition sites located in the middle of their dumbbell and thread components, respectively, and encircled by single cyclobis(paraquat-p-phenylene) rings have been synthesized under template control and their solid-state (super)structures have been solved. The investigations revealed that the stoppers on the dumbbell components, the solvents, and the counterions can affect the conformations adopted by the [2]rotaxanes and [2]pseudorotaxane in the solid state.
