摘要

在本論文中，我們成功以鹼金：鋰、鈉、鉀、銣、銫和鹼土金屬：鎂、鈣、鍶、鋇與各種羧酸配位基(蘋果酸、萘-1,4-二羧酸、4,4'-磺醯基二苯甲酸)，分別利用中溫水熱、微波加熱和直接混成合成法合成出十四個不同的新穎的有機骨架，其分子式分別為：
[Mg4(L-MA)2(HCO2)2(OH)2]‧(EtOH)‧2(H2O) (1)
[Mg(L-MA)(H2O)] (2) [Ca(L-MA)] (3)
{[Sr(L-MA)(H2O)3]‧H2O} (4) [Li(HNDA)(H2O) 2] (5)
[Na2(NDA)(DMF)] (6) {Mg2(NDA)2(H2O)2}‧H2O} (7)
[Ca(NDA)(DMF)] (8) [Sr(NDA)(DMF)] (9)
[Ba(NDA)(DMF)] (10) {[Na2(SBA)]‧0.7EtOH } (11)
[K4(H2O)(SBA)2(DMF) 0.5] (12) [Rb2(SBA)] (13)
{[Cs(HSBA)(H2O)]‧DMF } (14)
　　單晶X-ray繞射分析顯示化合物1 - 3、6 - 14都是三維骨架結構，化合物4、5是一維的骨架結構，其中化合物1、6、11、12、14為微孔結構，化合物3、11具結構的穩定性可高達350 oC。
　　以上的化合物除了以單晶X-ray繞射儀來鑑定其分子結構外，還利用其他的分析工具如粉末X-ray繞射分析、元素分析、熱重分析、紅外光光譜、紫外-可見光光譜、光激放光光譜、二氧化碳和氮氣的吸脫附來探討所有的化合物特性。

Fourteen new coordination polymers have been synthesized by hydrothermal reactions, microwave and directly synthesis with alkli (Li、Na、K、Rb、Cs), alkaline-earth metal (Mg、Ca、Sr、Ba) and three types carboxylic acid.
[Mg4(L-MA)2(HCO2)2(OH)2]‧(EtOH)‧2(H2O) (1)
[Mg(L-MA)(H2O)] (2) [Ca(H2L-MA)] (3)
{[Sr(L-MA)(H2O)3]‧H2O} (4) [Li(HNDA)(H2O)2] (5)
[Na2(NDA)(DMF)] (6) {Mg2(NDA)2(H2O)2}‧H2O} (7)
[Ca(NDA)(DMF)] (8) [Sr(NDA)(DMF)] (9)
[Ba(NDA)(DMF)] (10) {[Na2(SBA)]‧0.7EtOH} (11)
[K4(H2O)(SBA)2(DMF)0.5] (12) [Rb2(SBA)] (13)
{[Cs(HSBA)(H2O)]‧DMF } (14)
(DMF= N,N′-dimethylformamide; H2L-MA= L-malic acid; H2NDA= Naphthalene-1,4-dicarboxylic acid; H2SBA = 4,4'-sulfonyldibenzoic acid).
The single crystal structure analysis showed that compound 1 - 3, 6 - 14 are three-dimensional structures 4 and 6 are with one-dimensional chains. The highly structure thermal stability was observed for compounds 3 and 11 which are stable up to about 350 oC. These compounds were also characterized by powder X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectroscopy, UV-Vis spectra, photoluminescence, gas absorption.
