Main-chain liquid crystalline polymers (LCPs) have been widely investigated due to the excellent thermal stability and mechanical properties. In addition, hydrogen bond has been utilized to construct peptide supramolecular organogels by bottom-up approach but rarely to fabricate other supramolecular polymeric gels. In this work, some main-chain polymers with different proportion of pendent amide group have been designed and synthesized by melt polycondensation. The relationship between the liquid crystalline property and the proportion of amide group has been investigated by DSC and WAXD. Interestingly, among these polymers, the smectic main-chain LCP P₁₀₀ with the highest molar ratio of amide group displays the best gelation ability with a minimum gelation concentration (MGC) of 2 wt% in THF. The hydrogen bond has been proved to be one of the most important driving forces for the gelation by NMR technique. The organogels exhibit good self-supporting ability with a storage modulus higher than 10⁴ Pa when the gelator concentration is more than 4 wt%. At last, a hairpin model has been proposed to illustrate the microstructure for these organogels. These robust polymeric organogels that have been synthesized by bottom-up approach using hydrogen bond broaden the applications for main-chain LCPs ranging from actuators to electro-optical devices.

由于优异的热稳定性和机械性能，主链液晶聚合物（LCP）已被广泛研究。此外，氢键已被用于通过自下而上的方法来构建肽超分子有机凝胶，但很少用于制造其他超分子聚合物凝胶。在这项工作中，通过熔融缩聚反应设计并合成了一些具有不同比例的侧酰胺基的主链聚合物。通过DSC和WAXD研究了液晶性质与酰胺基团的比例之间的关系。有趣的是，在这些聚合物中，近晶主链LCP P ₁₀₀具有最高酰胺基团摩尔比的化合物显示出最佳的胶凝能力，在THF中的最小胶凝浓度（MGC）为2 wt％。通过NMR技术已经证明氢键是凝胶化的最重要的驱动力之一。当凝胶 剂浓度大于4wt％时，有机凝胶表现出良好的自支撑能力，其储能模量高于10 ⁴ Pa。最后，提出了一种发夹模型来说明这些有机凝胶的微观结构。通过使用氢键的自下而上方法合成的这些坚固的聚合物有机凝胶拓宽了从致动器到光电器件的主链LCP的应用范围。
