指導教授 : 曾添文

摘要


本研究以自組裝法製備錸金屬椅型、矩型及籠狀化合物之超分子,鑑定其結構並探討其性質。設計fac-(CO)3Re為超分子化合物之邊角,與提供三個電子之蟹合基配位,再與能提供兩個電子之架橋配位基結合,以滿足錸金屬十八個電子的穩定組態,以構築具有大洞穴之新型電中性錸金屬超分子1−5,分成 (一) 椅型超分子化合物1、2之合成:構成超分子的配位基分別 為 2,5-pyrazinedicarboxylic acid(2,5-H2pzdc)、 1,2-bis(benzimidazol-1-ylmethyl)benzen(1,2-bbim)、 1,3-bis(benzimidazol-1-ylmethyl)benzen(1,3-bbim) 。 取Re2(CO)10與這些配位基以水熱法合成得化合物[Re2(CO)6(1,2-bbim)(2,5-pzdc)](1)、[Re2(CO)6(1,3-bbim)( 2,5-pzdc)•C7H8](2). (二)矩型超分子化合物3、4之合成,構成超分子的配位基分別 為 Trans-1,2-Bis(4-prydyl)-ethylene(bpe)、 2,5-Dihydroxy-1,4-benzoquinone(dhb)、2,7-Diazapyrene。 取Re2(CO)10與這些配位基以水熱法合成得化合物[Re4(CO)12(2,7-Diazapyrene)2(OEt)4](3)、[Re4(CO)12(dhb)2(bpe)2(o-xylene)](4). (三)新形籠狀超分子化合物5之合成,構成超分子的配位基分別為 2,4,6-tri-4-pyridyl-1,3,5-triazine(TPT)、Indigo。 取Re2(CO)10與這些配位基以水熱法合成得化合物 [Re6(CO)18(TPT)2(Indigo)3] (5). 化合物1−5皆以元素分析、1H-NMR、TGA、IR、MASS、UV-Visible做性質鑑定,並經X-ray作晶體結構解析。最後再以TGA做熱穩定性探討,及發光性探討。 (一)椅型超分子化合物1和2之晶體數據如下: 化合物1: a = 11.6350(3) Å,b = 12.5300(3) Å,c = 14.9650(5) Å,α = 76.2380(10)

In the first part of this thesis, the rational design and self-assembly of rhenium-based supramolecules 1−5 are reported. Further characterization by IR, NMR, Mass and EA analyses have been carried out. The self-assembly of rhenium-based nanohost with a rectangular inner cavity was be achieved via a simple one-step synthetic route. The rational selection of fac-(CO)3Re as a corner, the judicial choice of a chelating ligand with three-electron donor, and a with bridging ligand two-electron donor can fulfill the eighteen-electron configuration around the rhenium metal center. As a result, the novel via self-assembly strategy rhenium-based Supramolecules 1−5 were successfully prepared.The products were characterized by X-ray crystallograpy and spectroscopy. The results of single-crystal X-ray diffraction analysis for the synthesized compounds 1−5 are described in three types as following: ( I ) Synthesis of Novel Chair form Supramolecules Compound (1): a = 11.6350(3) Å,b = 12.5300(3) Å,c = 14.9650(5) Å,α = 76.2380(10)
