Chromonics are a class of liquid crystals made of aqueous solutions of plank-like molecules, which self-assemble into semiflexible chains. At a given temperature a nematic phase is formed when the system reaches a sufficiently high concentration. Among the unusual properties of chromonic liquid crystals, particularly prominent is the large anisotropy of elastic constants, which leads to new phenomenologies in confined volumes. To gain insights into the microscopic origin of this behavior, we have investigated the elastic properties of a model system that undergoes self-assembly driven nematization by using Monte Carlo simulations and an Onsager-like theory. The relative magnitude of the elastic constants and their dependence on temperature and density show the distinguishing features found in chromonic liquid crystals. We identify the relevant microscopic determinants of this behavior, and we discuss the role played by both the molecular self-assembly and the intrinsic flexibility of aggregates.

发色液晶的弹性常数
色团是由板状分子的水溶液制成的一类液晶，它们自组装成半柔性链。当系统达到足够高的浓度时，在给定温度下会形成向列相。在发色液晶的不同寻常的特性中，特别突出的是弹性常数的大各向异性，这导致了有限体积内的新现象。为了深入了解这种行为的微观根源，我们使用蒙特卡罗模拟和类似Onsager的理论研究了模型系统的弹性特性，该系统经历了自组装驱动的线虫化。弹性常数的相对大小及其对温度和密度的依赖性显示了发色液晶中的显着特征。
