摘 要: 设计合成了m eso-四(间烷氧基苯基)卟啉及其19个铜配合物,其中16个为未见报道的化合物.研究了其合成、分离、纯化方法,得到了这两个系列化合物的晶体或固体,其结构经1H NMR,MS,IR,UV和元素分析确证.研究了这两个系列化合物的液晶性能,发现13个化合物具有液晶性,其液晶行为表现为升温单变液晶.还研究了烷氧基链长、金属离子和分子空间结构对卟啉化合物液晶性能的影响. meso-Tetrakis (3-alkoxyphenyl) porphyrin [meso-T (3-ROP) PH2] were synthesized by the condensation of 3-alkoxybenzaldehydes with pyrrole, reacted with copper (Ⅱ) acetates to form the corresponding complexes[meso-T(3-ROP)PCu]. Among them there are sixteen new compounds. For the first time, meso- T(3-ROP) PH2 and meso-T(3-ROP)PCu were generated as crystals or solids. Molecular structures of all the synthesized compounds were confirmed by IR, UV, I H NMR, MS and elemental analysis. Differential scanning calorimetry and polarizing microscope were used to probe the liquid crystal properties of the serial compounds. Thirteen compounds were found to exhibit liquid crystal properties. However, they displayed as heating monotropic liquid crystals. The effects of alkoxy chains, metal ions of complexes and molecular space structure on the liquid crystal properties were investigated.
