  Self-Assembly of Cationic, Hetero- or Homonuclear Ruthenium(II) Macrocyclic Rectangles and Their Photophysical, Electrochemical, and Biological Studies

  摘要：

  A series of supramolecular rectangles, including two mixed-metal Ru/Pt complexes, have been formed by the coordination-driven self-assembly of a range of arene-Ru "molecular clip" acceptors (la id) with rigid dipyridyl-based ligands (2a-2d) over the course of 10 h in solution. The isolated products were characterized by multinuclear NMR (H-1 and C-13 or P-31), HR-ESI-MS, and an X-ray diffraction study to support the ascribed two-component rectangular structures. The rectangles were further characterized by UV-vis and fluorescence studies. The redox behaviors of rectangles 3ca and 3da were also determined using cyclic voltammetry. Additionally, the antitumor activities of the suite of rectangles were determined against various human cancer cell lines, and significant activity was shown by complexes 3ca, 3da, 3cb, 3cc, and 3cd, with IC50 values as low as 2.65 mu M.

  Coordination-Driven Self-Assembly of Predesigned Supramolecular Triangles

  摘要：

  The design and self-assembly of three supramolecular triangles is described. A novel 601 corner unit directs the exclusive formation of triangular assemblies that are not in detectable equilibrium with other macrocycles. The resulting triangles have sides ranging from 2.7 to 3.5 nm in length and molecular masses as high as 5396 amu. The crystal structure of one of the assemblies shows an similar to1.4 nm cavity; the crystal packing forms open, triangular channels. The characterization of the supramolecular triangles by multinuclear NMR, elemental analysis, and electrospray mass spectrometry is also reported.
