supramolecular complexes of 2,4,6‐triarylamino‐1,3,5‐triazines (Tn) with semiperfluorinated benzoic acids have been prepared. The mesophase behaviors of such complexes were investigated with POM (polarized optical microscopy), DSC (differential scanning calorimetry) and X‐ray diffraction. Columnar mesophase was found in the equimolar mixtures of the triazines with the semiperfluorinated benzoic acids. While
的2,4,6-三芳基-1,3,5-三嗪(氢键键合的超分子复合物Ť Ñ)与semiperfluorinated苯甲酸已经制备。使用POM(偏振光学显微镜),DSC(差示扫描量热法)和X射线衍射研究了此类络合物的中间相行为。在三嗪与半全氟化苯甲酸的等摩尔混合物中发现了柱状中间相。三嗪与非氟化三倍烷氧基改性羧酸的等摩尔混合物不是介晶。分析中间相形成为T n之间的氢键苯甲酸导致离散的二聚体超分子并增强二聚体超分子的核心区域的极性;同时,当分子被半全氟化链取代后,分子内极性增加,这有利于微偏析,并导致柱状相的形成。
