摘　　要：合成了4个系列的8种对脂肪酰氧基苯基卟啉化合物.通过紫外-可见光谱、红外光声光谱、元素分析、核磁共振氢谱和质谱等分析手段进行了表征,并用DSC和偏光显微镜研究了它们的液晶行为.Four series of tetra(4 - n - alkanoyloxyphenyl) porphyrins (8 kinds) have been synthesized. The structures of the compounds are characterized by elemental analysis, UV - vis spectrum, FT - IR photoacoustic spectrum, IH NMR and MS. The domains of stability and the structure of the liquid crystalline phases are determined by optical microscopy and differential scanning calorimerials (DSC). These compounds melt to isotropic liquids well below their decomposition points and exhibit columnar discotic mesophase, lower phase transition temperature. The lowest is TLPPZn at - 36.4 degreesC.
