合成了 4个系列的中位 四 (对酰氧基苯基 )卟啉化合物。通过元素分析、紫外 可见光谱、红外光声光谱和核磁共振氢谱等分析手段表征了 4种卟啉自由碱化合物 ,并用DSC和偏光显微镜研究这些化合物的液晶行为 ,探讨了碳链长度对卟啉自由碱液晶性能的影响
Four series of intermediate tetra (p-acyloxyphenyl) porphyrin compounds were synthesized. Four kinds of porphyrin free base compounds were characterized by elemental analysis, UV-visible spectrum, infrared photoacoustic spectroscopy and 1H nuclear magnetic resonance spectroscopy. The liquid crystal behaviors of these compounds were also studied by DSC and polarized light microscope. The effects of carbon chain length on porphyrin Effect of free base liquid crystal properties
