Three series of {2-[3’-(N”-alkoxyphenyl)-5’-methyl-1’-pyrazolyl]ethyl ether}copper(Ι) tetrafluoroborates and two series of {2-[3’-(N”-alkoxy-phenyl)-5’-(N”-alkoxyphenyl)-1’-pyrazolyl]ethyl ether}copper(Ι) tetrafluoroborates were prepared and characterized. The previous three series of half-disk constructions of the ionic copper(Ι) complexes were obtained by reaction of 2-[3’-(N”-alkoxyphenyl)-5’-methyl-1’-pyrazolyl]ethyl ethers and [Cu(CH3CN)4]BF4 in acetonitrile, and the later two series of disk structures were under the same conditions using 2-[3’-(N”-alkoxyphenyl)-5’-(N”-alkoxyphenyl)-1’-pyrazolyl]ethyl ethers. These three-coordinated copper(Ι) complexes isolated, slightly green solids, were characterized by NMR spectroscopy and elemental analysis, and their mesomorphic properties were also studied by polarized optical microscope(POM), differential scanning calorimetry(DSC) and powder X-ray diffraction(XRD). Results indicated that these complexes exhibited disordered hexagonal columnar phases (Colhd). The clearing points were relatively low(81-112℃) and the temperature range of mesophases was ca. 45-68℃. The effect on the formation of mesophases by existence of methyl group will be studied as well in this thesis. In addition, the formation of mesomorphic properties on the numbers of side chains and the length of the carbon chains will be investigated in detail. Other relative researches will be in progress in our laboratory continuously. Chung K. Lai 賴重光 2001 學位論文 ; thesis 170 en_US |
