碩士 === 中國文化大學 === 應用化學研究所 === 96 === The goal of this thesis was to develop a self-assembly synthetic strategy for the preparation of rectangular metal-supramolecules and molecular triangles using 1,2-bis(4-pyridyl)ethane (bpe) and 1,3-bis(4-pyridyl)propane (bpe) as flexible ligands in a solvothermal method. Treatment of the organic ligands, 1,2-bis(4-pyridyl)ethane (bpe) and 1,3-bis-(4- pyridyl)propane (bpp), with Re2(CO)10 in the presence of methanol and buthanol under solvothermal conditions gave the rectangular compound, [Re4(CO)12(bpe)2 (OC4H9)4] (1) and triangular compound, [Re2(CO)6(bpp)(OCH3)2] (4), and an unexpected species, [Re2(CO)6(bpp)(ox)] (5). Treatment of Re2(CO)10, bpe、bpp and 2,2'-bisbenzimidazole (BiBzIm) or 2,5-dihydroxy-1,4-benzoquinone (DHBQ) afforded triangular complexes [Re2(CO)6(bpe)(BiBzIm)] (2)、[Re2(CO)6(bpp)(BiBzIm)]．0.25 (C8H10) (6)、[Re2(CO)6(bpp)(DHBQ)] (7), respectively. In particular, treatment of Re2(CO)10 、bpe and tetrahydroxy-p- benzoquinone (THBQ) afforded a bitriangular compound [Re4(CO)12(bpe)2(THBQ)]．(C6H6)2 (3). The products were characterized by spectroscopic methods and single-crystal X-ray diffraction analysis.
