摘要

在本篇論文中我們合成了四種雙亞胺酚基金屬錯合物 MII(saltBuenpy) (MII = ZnII, NiII, CoII, PdII)，也成功的利用鋅金屬錯合長出大環分子的四聚體[Zn(saltBuenpy)]4 之單晶結構。利用螢光光譜儀，分別探討鋅金屬錯合物Zn(saltBuenpy) 對硝基化合物、胺基化合物，以及不同鹽類的銀離子的螢光感測表現。實驗結果表現出鋅金屬錯合物對於硝基化合具有感測能力，產生螢光淬熄。在對胺基化合物做感測時，同樣的有產生螢光下降的結果，但無法在低當量數下完成檢驗。值得一提的是鋅金屬錯合物對4-胺甲基吡啶的感測為螢光增強。鋅金屬錯合物對銀離子的實驗中，除了醋酸銀之外的銀離子鹽類皆產生螢光淬熄，因此推測除了銀離子的辨識效應外，陰離子的存在對螢光亦存在干擾。

Four metal complexes of bis(salicyaldimine) dianion, MII(saltBuenpy) (MII = ZnII, NiII, CoII, PdII), have been synthesized and characterized. While Ni(saltBuenpy) exhibit a simple, well know structure in the solid-state, Zn(saltBuenpy) shows an interesting open vast structure of tetrameric assembly [Zn(saltBuenpy)]4 in the solid-state.
Photoluminescence studies of Zn(saltBuenpy) exhibit an aggregation-caused quenching (ACQ) effect in DMSO solution. Complex Zn(saltBuenpy) displayed sensing properties in detection of organic nitro compounds (nitrobenzene, NB; 1,4-dinitrobenzene, DNB; 4-nitrotoluene, NT; 2,4-dinitrotoluene, DNT; nitromethane, NM; 2,3-dimethyl-2,3-dinitrobutane, DMDNB) and amines (aniline; m-phenylenediamine; 1-butanamine; 4-aminopyridine; 3-(aminomethyl)pyridine; 4-(aminomethyl)pyridine) through fluorescence quenching, except in the case of 4-(aminomethyl)pyridine that causes fluorescence enhancement.
In addition, Zn(saltBuenpy) can also be used to detect Ag+ salts of different anions, as a result of noticeable fluorescene quenching, with exception of Ag(OAc). Detailed studies confirm that anions have interference upon detection of fluorescence change in intensity.
