Self-supporting liquid crystalline physical gels with facile electro-optic response are highly desirable, but their development is challenging because both the storage modulus and driving voltage increase simultaneously with gelator loading. Herein, we report liquid crystalline physical gels with high modulus but low driving voltage. This behavior is enabled by chirality transfer from the molecular level to three-dimensional fibrous networks during the self-assembly of 1,4-benzenedicarboxamide phenylalanine derivatives. Interestingly, the critical gel concentration is as low as 0.1 wt %. Our findings open doors to understanding and exploiting the role of chirality in organic gels.

具有高模量但驱动电压低的手征性液晶物理凝胶

具有易于电光响应的自支撑液晶物理凝胶是非常需要的，但是它们的发展具有挑战性，因为储能模量和驱动电压都随着胶凝剂装载量的增加而同时增加。本文中，我们报道了具有高模量但驱动电压低的液晶物理凝胶。在1,4-苯二甲酰胺基苯丙氨酸衍生物的自组装过程中，从分子水平到三维纤维网络的手性转移使这种行为成为可能。有趣的是，临界凝胶浓度低至0.1重量％。我们的发现为理解和利用手性在有机凝胶中的作用打开了大门。
