dc.description.abstract | 本文使用過渡金屬離子和 4-amino-3,5-bis(4-pyridyl)-1,2,4-triazole (4-bpt)經
由 自 組 裝 的 方 式 合 成 出 {[Cd(4-bdt)(atpa)(H2O)]·(DMF)(H2O)2}n (1),
{[Cd(4-bdt)(htpa)(H2O)]·DMF}n (2), {[Cd(4-bdt)(ntpa)(H2O)]·DMF}n (3),
{[Zn(4-bdt)(2,5-tdc)]·DMF}n (4), {[Zn(4-bdt)(cca)2]·DMAC}n (5),
{[Cu(4-bdt)2(H2O)]·(DMAC) (EtOH)0.5(H2O)3(NO3)2}n (6)等六個化合物,並以單晶
X-ray 繞射解析其結構,以螢光光譜法及氣體吸附實驗,探討各化合物的物理性
質。
鎘金屬離子和 4-bpt 配子於二甲基甲醯胺和水的混合溶劑中,分別與
2-aminoterephthalic acid (atpa) 、 2-hydroxyterephthalic acid (htpa) 或
2-nitroterephthalic acid (ntpa)以水浴法反應各得到化合物 1-3。化合物 1-3 為相
似的結構,都是以鎘金屬中心形成之二維平面,層與層間藉由氫鍵作用力形成三
維的超分子架構。化合物 1-3 中皆具有一維孔道,故進一步進行氣體吸附性質
之探討。
硝酸鋅金屬鹽類與 4-bpt 配子分別與 2,5-thiophenedicarboxylic acid (2,5-tdc)
或 4-carboxycinnamic acid (cca)兩種不同的羧酸根配子反應,各得到以鋅金屬離
子為基底的化合物 4 或 5,產物經由紅外線光譜、元素分析與單晶 X 光與粉末繞
射儀來鑑定結構,化合物 4 和 5 均為三維結構,其配位模式都非常類似於
paddle-wheel 的形式,兩個鋅金屬離子先與四個羧酸根上的氧原子配位,形成二
維的平面,再由 4-bpt 扮演著 pillar 的角色以氮原子與鋅金屬離子橋接而構成三
維的網狀結構,使化合物 4 和 5 都具有孔洞,此外化合物 4 和 5 都具有互穿的特
性,二氧化碳的氣體吸附性質也一併研究。
化合物 6 則以六配位之銅金屬中心形成二維平面,再透過氫鍵作用力及二次
互穿形成三維的超分子架構。 | zh_TW |
dc.description.abstract | In this thesis, a series of supramolecular compounds and coordination polymers
were synthesized via self-assembly processes and their structures and properties were
examined.
Compounds {[Cd(4-bdt)(atpa)(H2O)]·(DMF)(H2O)2}n (1),
{[Cd(4-bdt)(htpa)(H2O)]·DMF}n (2), {[Cd(4-bdt)(ntpa)(H2O)]·DMF}n (3),
respectively, were produced by the reaction of cadmium salts,
4-amino-3,5-bis(4-pyridyl)-1,2,4-triazole (4-bpt), and 2-aminoterephthalic acid (atpa),
2-hydroxyterephthalic acid (htpa) or 2-nitroterephthalic acid (ntpa) ligands in a mixture
of DMF/H2O at 50 °C. The structures of compounds 1, 2, and 3 are similar. They are
comprised of two-dimensional structures formed by seven-coordinated metal centers,
and three-dimensional supramolecular structures are formed by hydrogen bonding
interactions between the two-dimensional structures. Because the structure has a
one-dimensional channel, it has gas adsorption characteristics.
A series of zinc-based metal-organic frameworks {[Zn(4-bdt)(2,5-tdc)]·DMF}n
(4), {[Zn(4-bdt)(cca)2]·DMAC}n (5) were synthesized at 50 °C. The structures of the
two products were constructed from paddle-wheel units, which were formed from two
zinc ions, four carboxylates and two pyridine united. The properties of compounds 4
and 5 regarding the uptake of CO2 are also discussed.
The reaction of Cu2+ with 4-bpt in a mixture of DMAC/H2O/EtOH at room
temperature resulted in the formation of {[Cu(4-bdt)2(H2O)]·(DMAC)
(EtOH)0.5(H2O)3(NO3)2}n(6). Compounds 16 were characterized by infrared
spectroscopy (FT-IR), powder X-ray diffraction (PXRD), elemental analysis (EA),
and thermogravimetric analysis (TGA). Their structures were further confirmed by
single-crystal X-ray diffraction analysis. | en_US |
