碩士 === 國立中央大學 === 化學學系 === 101 === 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.
