摘　　要：以3,5-二甲氧基苯甲醛和吡咯为原料,经缩合反应制得meso-5,10,15,20-四(3,5-二甲氧基苯基)卟啉(1);1与BBr3反应制得meso-5,10,15,20-四(3,5-二羟基苯基)卟啉(2);2与辛酰氯反应制得meso-5,10,15,20-四[3,5-二(辛酰氧基)苯基]卟啉(3);3分别与ZnCl_2和CuCl_2经配位反应合成了meso-5,10,15,20-四[3,5-二(辛酰氧基)苯基]卟啉锌配合物(4)和meso-5,10,15,20-四[3,5-二(辛酰氧基)苯基]卟啉铜配合物(5),其结构经FL,UV-Vis,1H NMR,IR和元素分析确证。采用差示扫描量热法(DSC)和偏光显微镜研究了4和5的性能。结果表明:4和5为双变液晶,初始转变温度分别为31℃和28℃。5,10,15,20-Tetra（ 3,5-dimethoxylphenyl） porphyrin（ 1） was obtained by condensation reaction of pyrrole with dimethoxy benzaldehyde. 1 reacted with BBr3 to form 5,10,15,20-tetra（ 3,5-dihydroxylphenyl） porphyrin（ 2）,and 2 reacted with caprylyl chloride to form 5,10,15,20-tetra（ 3,5-dioctylacyoxyphenyl） porphyrin（ 3）. Zinc porphyrin complexe（ 4） and copper porphyrin complexe（ 5）were synthesized by metallization of 3 with ZnCl2 and CuCl2,respectively. The structures were confirmed by FL,UV-Vis,1 H NMR,IR and elemental analysis. The optical properties,thermal stability and liquid crystalline properties of 4 and 5 were investigated by DSC and polarized optical microscope.The results showed that 4 and 5 were dual variable liquid crystals. The initial transition temperatures of 4 and 5 were 31 ℃ and 28 ℃,respectively.
