摘要:	本篇論文分為兩個部分：第一部分為使用ZIF-8此種微孔洞結晶，將其鍵結在中孔洞矽材SBA-15或是MCF-17上，合成出一種新穎的孔洞分級材料。並利用固態核磁光譜、FT-IR等儀器確認是否成功合成，再以等溫氮氣吸脫附儀、SEM及熱重分析儀研究其孔洞大小與性質。未來希望可以將其應用在氣體的分離或是吸附上。第二部分為延續已畢業學長蕭家騰所做的具環狀結構之中孔洞矽材的研究。由學長以及同學的努力，已經得知此種具環狀官能基之中孔洞材料對於鑭系元素有不錯的吸附效果，由以鐿離子的吸附性最佳，可達到約180μg/mg。另外吸附釓離子的環狀中孔洞材料也被證實其具有做為顯影劑的潛能。本實驗則將中孔洞矽材的大小，減縮至200 nm左右，且使用此種奈米中孔洞矽材製作其中一種環狀中孔洞材料：3C-CAR-10-NPs，並以固態核磁光譜確認其結構。期待未來能將之應用在顯影劑的細胞實驗上。 Two parts in this thesis: Part I, we have reported for the first time a hierarchical micro-/mesoporous structure synthesized by heteroepitaxial growth of microporous zeolitic imidazolate framework-8 (ZIF-8) on mesoporous via heterogeneous phase synthesis. A detailed characterization of the samples performed using different spectroscopic techniques unanimously demonstrated the growth of a hybrid micro-/mesoporous structure. Furthermore, scanning electron microscopy also confirmed that the obtained products were microscale and nanoscale ZIF-8 formed on the surface raft of mesoporous MCF-17. Those novel porous materials are expected to provide new dimensions for the use of porous materials in applications such as gas adsorption, separation, and catalysis. Part II, we also reported a series of novel mesoporous silica possessing functional annular rings obtained by post-synthesis grafting with diamines. These materials obtained open auxiliary avenues for selective lanthanide ion absorption via manipulation of the annular ring size. The annulated mesoporous obtained from 1, 3-diaminopropane, 3C-CAR-10 showed high Yb+3 adsorption (~180μg/mg). Additionally, Gd+3 ions chelated with the annulated mesoporous as Gd@annular-mesoporous may be potentially applied in new generation MRI contrast agents. Finally, the synthetic CAR-10 nanoparticles exhibited a homogeneous particle size of 200 nm. The nanoscale parent materials for annulated modification were successfully synthesized for further in vivo applications.
