含三嗪單元之共價有機框架及聚合物:合成與孔洞特性研究

Triazine-based Covalent Organic Framework and Polymers: Synthesis and Porosity Studies

指導教授 : 賴榮豊

摘要


本論文分為二部份。第一部分,我們將本實驗室過去合成的大環分子(2Baf-4NH-2Cl)進行修飾,利用4羥基苯甲醛取代大環分子上的氯原子,使其在堆疊時能夠擴大吸附二氧化碳的孔洞面積。而延長大環分子的分枝後,成功的提升其 BET 比表面積(可達281.2 m2/g)。而使用二乙醇胺取代大環分子上的氯原子時,我們發現該大環分子則具有吸附界面活性劑(SDS)的能力。 論文的第二部分我們成功合成了一系列的共價有機聚合物。以三嗪為核心,使用不同比例的4,4’-聯哌啶、哌嗪或2,7-二氮雜螺[4.4]壬烷二氫溴酸鹽作為連接基與三嗪進行聚合反應,所得的聚合物產物不僅有良好的二氧化碳吸附能力,BET比表面積達到458.8 m2/g,此外,我們還發現其具有捕捉水中金屬離子的能力,尤其是對鐵離子,有較佳的吸附能力。

This thesis consists of two part. In the first part, we have previously prepared the macrocyclic molecule (2Baf-4NH-2Cl) in our laboratory and now replaced the Cl of the macrocyclic molecule with 4-Hydroxybenzaldehyde by 4-Hydroxybenzaldehyd. After extending the branches of the macrocyclic molecules , we hope to increase the carbon dioxide adsorption capacity and the BET surface area. In the second part of the thesis, we successfully synthesized a series of covalent organic polymers by using triazine as the core and different ratios of 4,4'-bipiperidine, piperazine or 2,7-diazaspiro[4.4]nonane dihydrobromide as the linking group for polymerization reaction. One of the polymer products has good CO2 adsorption capacity, and the BET surface area reaches 458.8 m2/g. In addition, we also found that it has the ability to capture metal ions in water, especially for iron ion in the water.
