摘要
合成了meso-四(邻烷氧基苯基)卟啉及其铜配合物两个系列20个化合物,其中未见文献报道的化合物16个,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,用1HNMR,MS,IR,UV,元素分析等方法确证了这些化合物的结构.用差示扫描量热法(DSC)和偏光显微镜(PM)研究了这两个系列化合物的液晶性能,发现19个化合物具有液晶性,其液晶行为表现为升温单变液晶.
A series of meso-tetrakis（2-alkoxyphenyl）porphyrin derivatives [（ROPh）4PH2] and their copper（Ⅱ） complexes [（ROPh）4PCu] were synthesized, and sixteen of them were new compounds. For the first time, [（ROPh）aPH2] and [（ROPh）aPCu] were generated as crystals or solids. The ^1H NMR, mass, FTIR, UV-Vis spectra and elemental analysis data were in good agreement with the assigned structures. The liquid crystalline （LC） properties of twenty compounds were studied by differential scanning calorimetry and polarizing microscope. It was observed that nineteen of them behaved as LC in a wide range of temperature. However, they displayed as heated monotropic liquid crystals.
