合成了meso-四(对烷氧苯基)卟啉及其Cu,Co,Zn,Pb金属配合物38个,其中14个为未见文献报道的新化合物.用元素分析,IR,UV,~1H NMR,MS对其进行了表征,确证了其结构.研究了这五个系列化合物的液晶性能,发现16个化合物具有液晶性,探讨了烷氧基链长及配位金属离子对液晶性能的影响. Thirty-eight compounds of meso-tetrakis (p-alkoxyphenyl) porphyrins and their Cu, Co, Zn and Pb metal complexes were synthesized, of which 14 were new compounds which were not reported in the literature.Using elemental analysis, IR, UV, 1H NMR, MS, and their structures were confirmed.The liquid crystal properties of these five compounds were investigated and 16 compounds were found to have liquid crystallinity. The effects of alkoxy chain length and coordination metal ions on liquid crystal properties influences.
