合成了八(十二烷基)四氮杂茂氮(C_&lt；12&gt；)_8P_ZH_2及其相应的金属(II)配合物(C_&lt；12&gt；)_8P_ZM、M：铜、镍、钴、八(2-乙叉基)四氮杂菲(2-ETC_6)_8P_ZH_2和相应的铜(II)配合物(2-ETC_6)_8PzCu，并对其液晶态进行了表征。将这些性质与相应的多聚醛菁类进行了比较。无金属的(C_&lt；12&gt；)_8p_ZH_2衍生物形成类似(C_&lt；12&gt；)_8PcH_2的六方无序柱状中间相(D_&lt；HD&gt；)，而(C_&lt；12&gt；)_8p_ZM(M：Cu，Ni，Co)导致中心矩形无序柱状中间相(D_&lt；RD&gt；)。支链取代的金属自由衍生物(2-ETC_6)_8P_ZH_2形成四方相中间相As(2-ETC_6O)_8PcCu形成斜交的中间相，而(2-ETC_6O)_8PzCu形成未知液晶。四苯并吡嗪并卟啉化合物是第一个pi受体柱状介晶，(C&lt；12&gt；)_8p_zH_2的半波还原电位为-0.41V，(C_&lt；12&gt；)_8P_zm(M：Cu，Ni)的半波还原电位为-0.55V。合成了(2-ETC_6O)_8PcH_2和(2-ETC_6O)_8PcZn.Octakis(烷氧基苯基)-邻苯二甲酸二异氰酸酯((C_NOph)_8PcH_2=8、10、12和18)及其相应的铜(II)配合物((C_NOph)_8PcH_2n=10、12和18)和Oktakis(2-乙基己基)PCH_2，并对它们的介晶性进行了表征。(C_NOph)_8PcH_2(n=12和18)为六方无序柱状液晶，(C_NOph)_8PcCu(n=12和18)为矩形无序柱状液晶。合成了烷基苯氧甲基衍生物(C_&lt；12&gt；phOCH_2)，考察了侧链与邻苯二甲酸大环之间的连接键对其介晶性的影响。

Octa (dodecyl) tetrapylazitioporphylazine (C_<12>)_8P_zH_2, the corresponding metal (II) complexes (C_<12>)_8P_zM, M : Cu, Ni, Co, octa (2-etliylliexyl) tetrapylazinoporphyrazine (2-EtC_6)_8P_zH_2 and the corresponding copper (II) complex (2-EtC_6)_8PzCu have been synthesized and their liquid crystalline statescharacterized. These properties have been compared to those of the corresponding plillialocyanines. The metal free (C_<12>)_8P_zH_2 derivative forms a hexagonal disordered columnar mesophases (D_<hd>)like (C_<12>)_8PcH_2, whereas (C_<12>)_8P_zM (M : Cu, Ni, Co) lead to centered rectangular disordered columnar mesophases (D_<rd>). The branched chain substituted metal free derivative (2-EtC_6)_8P_zH_2 leads to a tetragonal mesophase as (2-EtC_6O)_8PcCu forms an oblique mesophase, whereas (2-EtC_6O)_8PzCu leads to an unidentified liquid crystal. The tetrapyrazinoporphyrazine compounds are the first pi-acceptor columnar mesogens ; the half-wave reduction potentials are -0.41V for (C_<12>)_8P_zH_2 and -0.55V for (C_<12>)_8 P_zM (M : Cu, Ni). In comparison, plitalocyanine derivatives are reduced at -0.94V for (2-EtC_6O)_8PcH_2 and -1.05V for (2-EtC_6O)_8PcZn.Octakis (alkyloxyphenyl) -phtarocyanine derivatives ( (C_nOph)_8PcH_2=8, 10, 12 and 18), their corresponding copper (II) complexes ( (C_nOph)_8PcH_2n=10, 12 and 18) and oktakis (2-ethylhexyl) PcH_2 have been synthesized and their mesomorphic properties characterized. (C_nOph)_8PcH_2, (n=12 and 18) exhibit hexagonal disordered columnar mesophases where (C_nOph)_8PcCu(n=12 and 18) yields a rectangular disordered columnar liquid crystal. Analkylphenyloxymethyl derivative, (C_<12>phOCH_2, was synthesized to determine the influence of the connecting link between the side chains aild the phtalocyanine macrocycle on the mesomorphic properties.
