中文摘要：

以Kumada偶联反应为关键步骤首次合成了未见文献报道的2,4-二胺基-6-（4,5-二癸基噻吩）-1,3,5-三嗪（T）,并制备了在多重氢键作用下T与全氟链苯甲酸（A）形成的超分子液晶复合物.红外光谱（IR）与偏光显微镜（POM）研究表明T与A形成的等摩尔复合物可呈现液晶柱相,其原因可能是T与A通过氢键形成的二聚超分子的中心极性区域由于氢键的存在其极性得到加强,以及全氟链的引入提高了分子内的极性对比,利于微观相分离及分子进行有序自组装.

英文摘要：

New thiophene diaminotriazine bearing two alkyl chains in the thiophene ring has been synthesized via Kumada coupling reaction as the key step.Its supramolecular liquid crystalline complex with semiperfluorinated benzoic acids has been prepared and the structure and mesophase characterization of this complex were investigated with infrared spectra and POM.Columnar mesophase was found in this complex.It is presumed that the hydrogen bonding between the diaminotriazine and benzoic acid leads to discrete dimeric supermolecule and enhances the polarity of the core region of the dimeric supermolecule;simultaneously,an increased intramolecular polarity contrast caused by semiperfluorinated chains favors a microsegregation,leading to the fromation of the columnar phase.
