Abstract

This study presents 13 new organic compounds with self-assembling behavior, which can be divided into two groups. The first synthesized group includes compounds based on 4'-(trifluoromethoxy)-[1,1'-biphenyl]-4-yl-4-(trifluoromethoxy) benzoate core, and the second includes compounds based on 4-((4-(trifluoromethoxy)phenyl)ethynyl)phenyl-4-(trifluoromethoxy) benzoate core. They differ in the number and location of the fluorine atom in the lateral position. Mesomorphic properties, phase transition enthalpies, refractive indices, birefringence, and MWIR (mid-wavelength infrared) spectral properties of the compounds were investigated, and the results were compared with currently used materials. The influence of the length of the core as well as type and position of substituents in the molecular core was analyzed. The lack of aliphatic protons in the molecular structure generated unique infrared properties.

摘要

本研究展示了13种具有自组装行为的新型有机化合物，它们可分为两组。第一组合成的化合物以4'-(三氟甲氧基)-[1,1'-联苯]-4-基-4-(三氟甲氧基)苯甲酸酯为核心，第二组以4-((4-(三氟甲氧基)苯基)乙炔基)苯基-4-(三氟甲氧基)苯甲酸酯为核心。它们在侧向位置的氟原子数量和位置上有所不同。研究了这些化合物的介晶性质、相变焓、折射率、双折射和中波红外（MWIR）光谱性质，并将结果与目前使用的材料进行了比较。分析了核心长度以及分子核心中取代基的类型和位置的影响。分子结构中脂肪族质子的缺乏产生了独特的红外性质。
