摘要

本論文分成兩大部份加以敘述：
(一)錸金屬籠狀化合物之超分子
本研究以自組裝法製備錸金屬籠狀化合物之超分子。設計fac-(CO)3Re為超分子化合物之邊角，與提供三個電子以蟹合方式配位之配位基，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。構成超分子的配位基分別為1,2,4,5-tetrakis(4-pyridyl-vinyl)benzene (tkpvb)、5,8-dihydroxynaphthoquinone (dhnq)，取Re2(CO)10與這些配位基以水熱法合成得化合物[{(CO)3Re(µ2-dhnq)2-Re(CO)3}2(µ4-tkpvb)2] (1) ，鑑定其結構並探討其性質。

(二)含triazole配子自組裝合成配位聚合物
探討2-amino-5-carboxylic acid-1,3,4-triazole及混配子1,2,4,5-benzenetetracarb-oxylic acid (1,2,4,5-btec)和1,3,5-benzenetricarboxylic acid (1,3,5-btc)與鋅、銅自組裝反應，並研究生成的配位聚合物結構與各性質。

Rhenium-based cage and coordination polymers were synthesized using a self-assembly strategy and their structures characterized. The content of this thesis can be summarized as follows.
(1) Self-assembly of the rhenium-based cage, [{(CO)3Re(µ2-dhnq)2-Re(CO)3}2(µ4-tkpvb)2](dhnq = 5,8-dihydroxynaphthoquinone; tkpvb = 1,2,4,5-tetrakis(4-pyridylvinyl)benzene) from Re2(CO)10 and tkpvb in the presence of dhnq under solvothermal conditions was achieved. Two tkpvb ligands were coordinated to four {(CO)3Re(dhnq)2Re(CO)3} edge moieties, thereby forming a tetragonal cage. This synthetic approach allows us for preparation of predictable, highly symmetrical nanoscopic structures.
(2) Synthesis of coordination polymers. Self-assembly of a series of nanometer-sized inorganic-organic hybrid materials from zinc, copper ions and 1,2,4,5-btec and 1,3,5-btc was achieved ligands. The structures of these materials were characterized by single-crystal X-ray diffraction analysis. The thermal stabilities and photophysical properties were also analyzed.
