  基于螺旋烯的配位笼中的手性自我歧视和宾客识别

  摘要：

  手性纳米级禁闭对于生物系统中的对映选择性识别和反应控制起着重要作用。超分子自组装可访问具有可调大小和特性的人工模拟物。在此，介绍了一种基于手性[6]螺旋烯骨架的[Pd 2 L 4 ]配位笼的新家族。双单齿吡啶基配体L 1的外消旋混合物在手性自识别下与Pd II阳离子选择性组装成非手性介观笼，顺式[Pd 2 L 1 P 2 L 1 M 2 ]。对映体L 1形成同手性笼[Pd 2 L 1 P / M 4 ]。较长的衍生物L 2形成具有较大空腔的手性笼[Pd 2 L 2 P / M 4 ]，它们结合具有不同亲和力的手性客体的旋光异构体。由于其独特的手性，该笼子可以区分不同长度的非手性客体，因为发现它们在螺旋形螺距的调节下挤压或拉长了空腔。CD光谱结果得到离子迁移质谱的支持。

The nanocage has been characterized by NMR spectroscopy, ESI-MS, and single-crystal XRD techniques. The confined nanospace of the cage has been utilized to encapsulate nonpolar/polar/anionic-aromatic

  Controlling supramolecular systems between different functional forms by utilizing acids/bases as stimuli is a formidable challenge, especially where labile coordination bonds are involved. A pair of acid/base responsive, interconvertible 1,5‐enedione/pyrylium based Pd2L4‐type cages are prepared that exhibit differential guest binding abilities towards disulfonates of varied sizes. A three‐state switch has been achieved, where (i) a weakly coordinating base induced cage‐to‐cage transformation in the first step, (ii) a strongly coordinating base triggered cage disassembly as the second step, and (iii) the third step shows acid(strong) promoted generation of initial cage, thereby completing the cycle. To our surprise, binding of a specific disulfonate guest facilitated cage‐to‐cage transformations by inducing strain on the cage assembly thereby opening the labile pyrylium rings of the cage. Through competitive guest binding study, we demonstrated superior guest binding capability of octa‐cationic pyrylium‐based cage over a similar‐sized tetra‐cationic cage. These results provide a reliable approach to reversibly modulate the guest binding properties of acid/base‐responsive self‐assembled coordination cages.
