    摘要: 過渡金屬錯合物中,多吡啶配位子是重要的角色,因它有共振的α-双亞胺基,可和金屬形成鉗合環,表現準芳香性質,具特異的電化學活性、長生命期和低能發射的光物理性質,本計畫即開發新型的此類配位子及相關錯合物,配位子中包括引入不同含氮雜環的配位官能基,如萘啶、嘧啶、吡咯、咪唑等,與不同金屬離子,如釕、銅、銀、金、鎳、鈷、鋅等。並應用於超分子及液晶方面。 超分子化學是目前化學研究最重要的課題之一,基於我們研究群已經開發出的腙基多吡啶配位的螺旋超分子金屬錯合物系統,將以此為基礎進行本研究計劃。計劃中將合成新穎超分子,特別是具多核金屬簇狀的中心軸的架構,鑑定其結構及基本光譜學性質及化學性質,探討其電化學性質、氧化還原性質、熱力學性質、光物理及光化學性質、自我組裝程序、晶體工學性質,以及上述性質之量子力學理論計算研究。 應用研究中包括了新穎液晶材料、奈米金屬顆粒、分子導線之研究。液晶材料以桿狀及盤狀的多核錯合形式及氫鍵形式液晶為主要目標。
    Polypyridyl derivatives are one of the most important ligands to be used in coordination chemistry. Owing to their α-diimine moiety can form delocalized chelating ring with metal ion, these ligands present novel electrochemical and photophysical properties. Polypyridyl type ligands, including pyridyl, bipyridyl, phenanthrolyl, pyridazinyl, naphtharidyl, and imidazolyl group, and their metal complexes, including silver, copper, gold, zinc, nickel, cobalt, and ruthenium, will be synthesized and characterized. Supramolecular chemistry takes advantage of self-assembly to prepare large, discrete structures from relatively simple subunits and has been a rapid growth research field in recent years. Using metal-ligand interaction, pi stacking, and/or hydrogen bonds to link the various subunits together is the major strategy for the synthesis. Many elegant examples of supramolecular assemblies have been synthesized in my group. In supramolecular architectures, helicity can be introduced by conformational restrictions of macromolecules, inter- or intramolecular hydrogen bonds, or coordination to metal ions. Based on our preliminary results of hydrazone linking helical polypyridyl coordination complexes, the main target compound of this proposal is helical supramolecules. The proposal will be addressed on the development of these supramolecules from the basic research to new materials. The basic research will be involved in the synthesis, structure, spectroscopic properties, photophysics, electrochemical properties, thermodynamic properties, theoretical calculation, self-assembly process, and crystal engineering to conduct the molecular level information. The material research will be focus on the development of liquid crystal, nano-materials, molecular wire, nano-metal particle, and molecular sensing for metal ions and anions.
