  摘要：

  已合成并表征了简并萘 (NP) 穿梭和非简并单吡咯并四硫富瓦烯 (MPTTF)/NP 氧化还原可控开关形状的两站 [2] 轮烷。它们的哑铃形组分由沿其长度中断的聚醚链组成，由 (i) 两个富电子站 - 两个 NP 部分或一个 MPTTF 单元和一个 NP 部分 - 与 (ii) 刚性芳乙炔基或丁二炔基间隔物位于两个站，并由（iii）在哑铃的每一端灵活系绳的疏水塞终止。研究这种修饰是为了简化之前在相关双稳态 [2] 轮烷中观察到的分子结构和转换功能，在它们的站之间具有柔性间隔物并结合环双（百草枯-对亚苯基）（CBPQT4+）环。非简并 MPTTF-NP 开关被分离为接近无异构体的双稳态 [2] 轮烷。MPTTF 的使用消除了表征四硫富瓦烯 (TTF) 母体核心结构的顺/反异构化。此外，仅观察到一种平移异构体（> 95 < 5），令人惊讶的是在很宽的温度范围内（198-323 K），这意味着 CBPQT4+

  A Transition Metal Containing Rotaxane in Motion: Electrochemically Induced Pirouetting of the Ring on the Threaded Dumbbell

  摘要：

  In this work we describe a rotaxane in which a new type of motion, pirouetting of the wheel around its axle, can be electrochemically triggered. The rotaxane was synthesized by using the three-dimensional effect of copper(I). It incorporates both a hetero-biscoordinating ring (containing both 2,9-diphenyl-1,10-phenanthroline and 2,2':6',2"-terpyridine units) and a molecular string which contains only one 2,9-diphenyl-1,10-phenanthroline. Both ends of the string are functionnalized by a bulky stopper ( tris(p-tert-butylphenyl) (4-hydroxypbenyl)methane). Large molecular motions have been induced electrochemically in this molecule and were detected by using cyclic voltammetry. The driving force of the two rearrangement processes observed is the high stability of two markedly different coordination environments for copper(I) and copper(II) ions. In the copper(I) state, two phenanthroline units tone of the ring, one of the string) interact with the metal in a tetrahedral geometry (Cu-(4)(I)), whereas in the copper(II) state the five-coordinate geometry (Cu-(5)(II)) is due to the phenanthroline of the string and to the terpyridine of the ring. The kinetic rate constants of the two molecular motion processes (from Cu-(5)(I)) to Cu-(4)(II)) and fom Cu-(4)(II)) to Cu-(5)(II))) have been determined and both rates are much faster than the ones in previously studied analoguous systems. In addition, the rate of the pirouetting motion depends greatly on the copper oxidation state. The divalent four-coordinate copper complex (Cu-(4)(II))) rearranges in tens of seconds, whereas the monovalent five-coordinate copper system leads to the four-coordinate complex in the millisecond time scale.

  Base-catalyzed thiol-maleimide click chemistry has been applied to the synthesis of neutral donor–acceptor [2]rotaxanes in good yield. This method is extended further to the synthesis of a glutathione-functionalized [2]pseudorotaxane, a precursor to integrated conjugates of interlocked molecules with proteins and enzymes.
