新型meso-四(4-N-n-十二胺基磺酰苯基)四苯并卟啉的合成及其液晶性能

Synthesis and Liquid Crystalline Property of Novel meso-Tetrakis(4-N-n-dodecylaminosulfophenyl)tetrabenzoporphyrin

苯乙酸锌和邻苯二甲酰亚胺反应制得meso-四苯基四苯并卟啉锌(1);1酸化得meso-四苯基四苯并卟啉(2);2经氯磺化生成meso-四(4-氯磺基苯基)四苯并卟啉(3);3与n-十二胺反应合成了一种新型的苯并卟啉类化合物——meso-四(4-N-n-十二胺基磺酰苯基)四苯并卟啉(4),其结构经UV-Vis,1H NMR和IR表征。偏光显微镜和DSC检测结果表明:4具有液晶性能。

meso-Tetraphenyltetrabenzoporphyrinatozinc（1） was prepared by the reaction of zinc phenylacetate and phthalimide,and then acidized to obtain meso-tetraphenyltetrabenzoporphyrin（2）.The sulfonation of 2 with chlorosulfonic acid formed meso-tetrakis（4-chlorosulfophenyl）tetrabenzoporphyrin（3）.A novel benzoporphyrin compound,meso-tetrakis（4-N-n-dodecylaminosulfophenyl）tetrabenzoporphyrin（4）,was synthesized by the reaction of 3 with n-dodecylamine.The structure was characterized by UV-Vis,1H NMR and IR.The results showed that the 4 exhibits the speciality of liquid crystal behavior by determination with polarization microscope and DSC.
