摘　　要：合成了系列卟啉乙酸合锰配合物9个,其中6个为未见文献报道的新化合物.用UV,1HNMR,IR,MS,元素分析等表征确证了配合物的结构,总结了锰与卟啉类配体配合的IR,UV,1HNMR判据.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8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.meso-Tetrakis（4-alkoxyphenyl）porphyrins were generated by condensation of 4-alkoxybenzal-dehydes with pyrrole, followed by reaction with manganese acetate to form nine corresponding complexes. Molecular structures of all synthesized compounds were confirmed by IR, UV, ^1H NMR, MS spectra and elemental analysis. Characteristic spectrometric data of IR, UV, ^1H NMR related to their structures have been systematically analyzed. Differential scanning calorimetry and polarizing microscope were used to probe the liquid crystal properties of the serial complexes. Eight 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.
