文摘

Two sandwich-type mixed (phthalocyaninato)(porphyrinato) rare earth double-decker complexes, M(Pc)(TPP) [H₂Pc = phthalocyanine; H₂TPP = meso-tetra(phenyl)porphyrin] (M = Eu, Lu) (1, 2) were synthesized and the structure of Lu(Pc)(TPP) was characterized by X-ray single-crystal diffraction method. Crystal data: triclinic, space group , Z = 2, C₇₇H₄₅Cl₃LuN₁₂, M_r = 1419.57, a = 12.573(5), b = 12.911(5), c = 22.935(5) ?, ¦Á = 103.793(5)¡ã, ¦Â = 101.363(5)¡ã, ¦Ã = 93.682(5)¡ã, V = 3521(2) ?³, ¦Ì(Mo K¦Á) = 1.196 mm^?, F(000) = 1426, R = 0.0590, and wR = 0.1639 for 9745 observed reflections with I > 2¦Ò(I). X-ray analysis reveals that the coordination polyhedron adopts a slightly distorted square-antiprismatic structure around the metal center. Both phthalocyanine and porphyrin ligands are saucer-shaped, with the skew angle of the two ligand planes approximately 45¡ã. The self-assembled nano-structures of both complexes 1 and 2 were systematically investigated by electronic absorption and Fourier transform infrared (FT-IR) spectroscopy, transmission electronic microscopy (TEM), scanning electronic microscopy (SEM), and X-ray diffraction (XRD) techniques, revealing the effect of molecular structure on the dimension of self-assembled nano-structures.
