本論文利用吡啶雙羧酸：3,5-Py(CO2H)2、2,3-Py(CO2H)2 、3,4-Py(CO2H)2 、2,5-Py(CO2H)2 作為配位基 (L) 和 [Cu2(dppm)2(MeCN)2](BF4)2 金屬起始物 (M) 合成環狀金屬錯合物：[Cu2(dppm)2(μ-(3,5-Py(CO2)2))]2(BF4)2 (3(BF4)2)、[Cu2(dppm)2(μ-(2,3-Py(CO2)2))]2(BF4)2 (4(BF4)2)、[{Cu2(dppm)2}2(μ-(3,4-Py (CO2)2))]2(BF4)4 (5(BF4)4)、[{Cu2(dppm)2}2(μ-(2,5-Py(CO2)))]2(BF4)4 (6(BF4)4)、{Cu2(dppm)2}2(μ-(3,5-Py(CO2)))]2(PF6)2 (7(BF4)2)，之後使用金屬起始物 [Ag2(dppm)2(MeCN)2](BF4)2 (M) 與 4-Py(CO2H) 合成[{Ag2(dppm)2}2(μ-(4-Py(CO2)))]n (BF4)n (9(BF4)n) 結構。這些結構藉由單晶X-光繞射儀與氫光譜圖、磷光譜圖以及紅外光譜圖確定有合成出來，而這些結構為雙聚物((3(BF4)2) 、4(BF4)2、5(BF4)4、6(BF4)4、7(BF4)2)以及一為維無限延伸的Z字形鏈狀結構(9(BF4)n)。
當在 [{Cu2(dppm)2}(μ-(4-Py(CO2))]4(PF6)4 (8(PF6)4) 一方型環狀結構中加入NH4PF6 分子時，進行分子辨識實驗時，得到令人振奮的結果，可以發現磷光圖譜以及紅外光圖譜與顏色都有明顯的變化，可以推測 8(PF6)4 可以辨識NH4PF6 分子。
接下來使用 [{Cu2(dppm)2}(μ-(4-Py(CO2))]4(BF4)4 與 4.4‘-bipyridine以機動化學方式進行擴環反應。當 [{Cu2(dppm)2}(μ-(4-Py(CO2))]4(BF4)4 跟不同比例的4.4‘-bipyridine 進行反應後，其磷光圖譜以及紅外光圖譜與顏色都有明顯的變化，可以認為應有新結構的生成。

In here,we successfully using the the combination of a flexible ligand-capped dinuclear transition-metal acceptor [Cu2(dppm)2(NCMe)2](BF4)2 with tritopic monodentate-bidentate donors such as 3,5-,2,3-, 3,4-, 2,5-pyridyldicarboxylates produced metallacycles like [Cu2(dppm)2(μ-(3,5-Py(CO2)2))]2(BF4)2 (3(BF4)2), [Cu2(dppm)2(μ-(2,3-Py(CO2) 2))]2(BF4)2 (4(BF4)2), [{Cu2(dppm)2}2(μ-(3,4-Py(CO2)2))]2 (BF4)4 (5BF4)4), [{ Cu4(dppm)4}(μ-(2,5-Py (CO2)2))]2(BF4)2(6(BF4)4), [{Cu2(dppm)2}2 (μ-(3,5-Py(CO2)))]2(BF4)4 (7(BF4)4). When we changed dinuclear transition-metal acceptor [Cu2(dppm)2(NCMe)2](BF4)2 metal centers from Cu(I) to Ag(I) and [Ag2(dppm)2](BF4)2 reacted with 4-pyridylcarboxylates, it become a 2-D zigzag polymer. All new copmlexes were characterized by liquid-state NMR, liquid-state IR spectra. Single-crystal structure of each complex were determined by single-crystal diffraction data.
We put the NH4PF6 molecular to react with metallacyclic [{ Cu2(dppm)2}(μ-(4-Py (CO2)2))]4(PF6)4(8(BF4)4) as a chemical sensing test,and we got a exciting result that the 31P NMR、H NMR peak shift dramatically and the solution’s colar change a lot too, it seem that 8(BF4)4 could act as chemical sensor.
Next, a ring expention of [{Cu2(dppm)2}(μ-(4-Py(CO2))]4(BF4)4 and 4.4'-bipyridine was carried out in dynamic Chemical method. Then we combinated [{Cu2(dppm)2}(μ-(4-Py (CO2)2))]4(BF4)4 with different proportion of 4,4‘-bipyridine the phosphorescence spectrum and the infrared spectrum and color of the reaction were changed obviously, it can be considered that a new structure should be generated.
