meso-四(对烷氧基苯基)卟啉镁配合物的合成、表征和性能研究

Synthesis, Characterization and Properties of Metallic Magnesium Complexes of meso-Tetrakis(4-alkoxyphenyl)porphyrins

合成了一系列meso-四(对烷氧基苯基)卟啉镁配合物,用UV-Vis,1H NMR,IR,MS,元素分析等确证了配合物的结构,总结了镁与卟啉类配体配合的UV-Vis,1H NMR,IR数据.采用差示扫描量热法(DSC)和偏光显微镜(PM)研究了该系列配合物的液晶性能,发现6个配合物具有液晶性;考察了烷氧基链长、配位金属离子和分子空间结构对液晶性能的影响.

A series of magnesium complexes of porphyrins were synthesized.Molecular structures of all synthesized compounds were confirmed by UV-Vis,1H NMR,IR,MS techniques and elemental analysis.Characteristic spectrometric data of IR,UV-Vis,1H NMR related to their structures have been systematically analyzed.Differential scanning calorimetry（DSC） and polarizing microscope（PM） were used to probe the liquid crystal properties of the serial complexes.Six of the serial complexes were found to exhibit liquid crystal properties.The effects of alkoxy chains,metal ions of complexes and molecular space structure on liquid crystal properties have been investigated.
