摘要
合成了meso-四(邻烷氧基苯基)卟啉合钴配合物10个,其中未见文献报道的新化合物8个,研究了其合成、分离、纯化方法,首次得到了该系列化合物的晶体或固体。用1HNMR、MS、IR、UV、元素分析等表征确证了其结构,报道和解析了该类卟啉钴配合物的1HNMR特殊波谱现象。用差示扫描量热法(DSC)和偏光显微镜(PM)研究了该系列配合物的液晶性能,发现6个配合物具有液晶性。研究了烷氧基链长、金属离子和分子空间结构对卟啉液晶性能的影响,烷氧基链长的增加、金属配合物的形成有利于液晶性能的改善。
A serises of cobalt(Ⅱ) complexes of meso-tetrakis(2-alkoxyphenyl)porphyrin(meso-T(2-ROP)PCo) were synthesized, and meso-T(2-ROP)PCo were obtained as crystals or solids. Molecular structures of all synthesized compounds were confirmed by IR, UV, 1H NMR, MS and elemental analysis. Differential scanning calorimetry and polarizing microscope were used to probe the liquid crystal properties of the complexes. Six of the serial complexes were found to exhibit liquid crystal properties. The effects of alkoxy chains , metal ions in complexes and molecular space structure on liquid crystal properties have been investigated.
