碩士 === 國立暨南國際大學 === 應用化學系 === 107 === In the first part of this thesis, the macrocyclic molecule 2Boc-4NH-2Cl was successfully synthesized and then the colorless bulk crystals of 2Boc-4NH-2Cl was growth by recrystaling in THF and n-hexane. The crystal was determined as a 3D porous structure by the single crystal diffraction, which was constructed from the π-π, CH-π and hydrogen bonds. The BET surface area of the porous material is 152.7 m2/g (Langmuir: 213.4 m2/g) was measured by the gas adsorption. Significantly, the luminescence intensity of the crystal have obvious change with the solvent regulation. In the second part, a series of three-dimensional porous organic polymers were successfully prepared by using tetrakis (4-aminophenyl)methane as the center and triazine and piperazine as the linking groups. The experiment repeated with different regulation of the organic base and the inorganic base which would influence the rate of the polymerization reaction and the pore characteristics of the polymers. The CO2 gas results of all porous polymers exhibited the noticeably different of the surface area and porosity. We found that slow polymerization which was added sodium carbonate would help molecular arrange in order, but gel permeation chromatography demonstrated that add suitable triethylamine can rise the molecule weight up.
