Abstract

Thermal and mesophase behavior of four new series of hydrogen-bonded supramolecular complexes (I/II) were investigated by differential scanning calorimetry and phases identified by polarized light microscopy. All hydrogen-bonded complexes formed from 4-alkoxyphenylazobenzoic acid (I) and 4-(4'-pyridylazophenyl)-4''-alkoxybenzoates (II). The results revealed that the prepared complexes are dimorphic, possessing smectic C and nematic phases. The comparison, made between the present series and previously investigated simpler, I/III and angular, I/IV analogues, revealed that increasing the length of the mesogenic core and/or linearity of complex increase the stabilities of both the smectic C and nematic phases.

摘要

通过差示扫描量热法研究了四个新系列氢键超分子配合物（I/II）的热行为和中间相行为，并通过偏光显微镜鉴定了相态。所有氢键配合物均由4-烷氧基苯基偶氮苯甲酸（I）和4-（4'-吡啶基偶氮苯基）-4''-烷氧基苯甲酸酯（II）形成。结果表明，所制备的配合物具有双晶型，具有近晶C相和向列相。将本系列与先前研究的更简单的I/III和角型I/IV类似物进行比较，结果表明，增加介晶核的长度和/或配合物的线性会提高近晶C相和向列相的稳定性。
