摘要

Herein, we describe the design and synthesis of three tetranuclear complexes, [(Cp*Rh)(L-1)](4)(OTf)(4) (la, HL1 = 2-(pyridin-4-yl)-1H-imidazo [4,5-f] [1,10]phenanthroline), [(Cp*Ir)(L-1)](4)(OTf)(4) (1b), and [(Cp*Rh)(L-2)](4)(OTf)(4) (2, HL2 = 2-(4-(pyridin-4-yl)phenyl)-1H-imidazo [4,5-f] [1,10]-phenanthroline). Owing to the precise design of the phenanthroline-derived ligands, these complexes exhibit perfect square shaped structures with side lengths of 13.53, 13.57, and 17.95 angstrom, respectively. These molecules orderly align and assemble into square-shaped, one-dimensional nanotubes. The molecular structures and arrangement of the nanotubes were evidenced by single-crystal X-ray diffraction. Solution behavior was studied by NMR spectroscopy. Fourier transform infrared spectroscopy and elemental analysis were also employed to characterize these complexes.
