卟啉类化合物由于其独特的结构和特有的性能,使得它在众多领域受到人们的高度重视,有关研究非常活跃[1~2]。目前液晶卟啉的研究受到广泛关注,许多液晶卟啉已经被合成出来[3~4]。Shin-ichi等人于1990年研究了两个四(p-n-烷氧苯基)卟啉及其配合物的液晶性[5],Shimizu等人于1993年系统研究了四(对烷基苯基)卟啉的液晶性[6],这些现象引起了人们对卟啉类化合物液晶性能研究的极大兴趣。我们合成了十四种未见文献报道的新的CO2+、Cu2+、Zn2+、Pb2+四个系列的中位-四(对烷… 相似文献

中位-四(对烷氧苯基 )卟啉 Co2+、Cu2+、Zn2+、Pb2+配合物的合成与表征 总被引:1,自引:0,他引:1
Synthesis of fourteen new complexes of meso-tetrakis(4-alkoxyphenyl) porphyrins with Co2+, Cu2+, Zn2+, Pb2+ were presented in this paper.Meso-tetrakis (4-alkoxyphenyl) porphyrins were prepared by condensation of 4-alkoxybenzaldehydes with pyrrole, then treated with corresponding metallic acetate to produce mentioned complexes, IR, UV, 1H NMR, MS and elementary analysis were explored to confirm the structures of all theses new complexes.Characteristic spectrometric data of IR, UV, 1H NMR related to these complexes have been systematically summarized.Ten of the fourteen complexes were found to exhibit liquid crystal properties. 相似文献
