  Covalent Stabilization: A Sturdy Molecular Square from Reversible Metal-Ion-Directed Self-Assembly

  摘要：

  Supramolecular self-assembly using weak interactions under quasi-equilibrium conditions has provided easy access to very complex but often quite fragile molecules. We now show how a labile structure obtained from reversible transition-metal-directed self-assembly of rods and connectors serves as a template that can be converted into a sturdy structure of identical topology and similar geometry. The process consists of Cu(I)-catalyzed replacement of all rods or connectors terminated with pyridines for analogues terminated with ethynyls, converting dative N -> Pt+ bonds into covalent C-Pt bonds. The procedure combines the facility and high yield of reversible self-assembly with the robustness of covalent synthesis.

  Pyridine-terminated molecular rods and either (i) the cis-(dppp)(I)Pt(C≡C-triptycene-C≡C)Pt(I)(dppp) rod or (ii) the trans-(PEt3)2(I)Pt(C≡C-biphenyl-C≡C)Pt(I)(PEt3)2 rod assemble into macrocycles, characterized by NMR, ESI-IMS, and in two cases also single-crystal X-ray diffraction. The former form rectangles with bidentate phosphine-containing cis-coordinated Pt(II)-alkyne corners. In the latter,

  吡啶末端的分子棒和（i）顺式（dppp）（I）Pt（C≡C-三茂铁-C≡C）Pt（I）（dppp）棒或（ii）反式-（PEt 3）2（I）Pt（C≡C-联苯-C≡C）Pt（I）（PEt 3）2杆组装成大环，通过NMR，ESI-IMS表征，在两种情况下还进行单晶X射线衍射。前者形成具有二齿膦含顺式配位的Pt（II）-炔基角的矩形。在后者中，Pt中心对反式构型的偏爱推翻了三键对线性和NMR的偏爱，表明它们具有椭圆结构，具有交替的弯曲棒和弯曲的反式（C≡C）Pt（PEt 3）2（C≡C）组件，与密度泛函理论计算一致。
