摘　　要： 合成了一系列未见文献报道的μ-氧-双[meso-四(对烷氧基苯基)卟啉合铝(Ⅲ)]配合物.用UV-vis,1H NMR,IR,MS和元素分析对各个化合物的结构进行了表征和确认,发现在该系列配合物中两个卟啉分子通过Al—O—Al键形成二聚体.用差示扫描量热仪(DSC)和偏光显微镜(PM)研究了其液晶性,发现其中九个配合物具有液晶性,多为升温单变液晶,有一至两个中介相,有确定的相转变温度、热焓和相变区间.考察了取代基、金属离子和配合物的空间结构对液晶性能的影响. A series of novel μ-oxo-bis[rneso-tetrakis（4-alkoxyphenyl）porphyrin aluminum（Ⅲ）] were synthesized. Their molecular structures were characterized by UV-vis, ^1H NMR, IR, MS spectra and elemental analysis, the results show that there two porphyrin molecules linked across Al-O-Al bond to form a dimer. Differential scanning calorimetry （DSC） and polarizing microscope （PM） were used to study their liquid properties. Among them, nine are found to exhibit liquid crystal （LC） properties, and most of them displayed as heating monotropic liquid crystals. There are one or two mesophases and certain phase transition temperature, AH and temperature range of liquid crystal （AT）. The effects of alkoxy chains, metal ions of complexes and molecular space structure on liquid properties have been investigated.
