Achieving a coexistence of two or multiple phases of soft matters via a delicate trade‐off of free energy and long‐range order with one another has been inspiring abundant interest on fundamental sciences and engineering. In this work, a stable coexistence of the optically achiral‐anisotropic liquid crystalline nematic phase and the optically chiral‐isotropic liquid crystalline blue phase is proposed and demonstrated, with their distribution tailored in a micro‐pattern by the developed localized micro‐regional polymer templating technique. Such a stable patterned coexistence of the two different phases with a distinct molecular arrangement, optical chirality, and anisotropy is achieved depending on a delicate matching of the elastic energy on the interface between liquid crystals and polymer networks. In contrast to the majority of soft coexistence systems, a specific dynamic and reversible on–off response of chirality and anisotropy is observed in such a system driven by an electric field. The structure of patterned coexistence system in the presence and absence of external stimulation is explored by microscopy and optical technique, and furthermore, the prospective photonic applications are demonstrated. This investigation indicates another category of functional soft material with fantastic adaptive characteristics for application in optics, electronics, interface physics, and chemistry.

手性-各向异性和手性-各向同性软材料图案共存中的手性和各向异性的可逆开关

通过自由能量和远程顺序的微妙权衡，实现软物质的两个或多个阶段的共存，已经激发了对基础科学和工程学的浓厚兴趣。在这项工作中，提出并证明了光学非手性各向异性液晶向列相和光学手性各向异性液晶蓝色相的稳定共存，并通过开发的局部微区域聚合物模板在微模式中定制了它们的分布。技术。根据液晶和聚合物网络之间界面上弹性能的精细匹配，可以实现具有不同分子排列，光学手性和各向异性的两种不同相的这种稳定的图案化共存。与大多数软共存系统相反，在这种由电场驱动的系统中，观察到了特定的动态和可逆的手性和各向异性的开-关响应。通过显微镜和光学技术探索了在有无外部刺激的情况下，图案化共存系统的结构，并证明了其在光子学中的应用前景。该研究表明另一类功能性软材料具有出色的自适应特性，可用于光学，电子，界面物理和化学领域。通过显微镜和光学技术探索了在有无外部刺激的情况下，图案化共存系统的结构，并证明了其在光子学中的应用前景。这项研究表明另一类功能性软材料具有出色的自适应特性，可用于光学，电子，界面物理和化学领域。通过显微镜和光学技术探索了在有无外部刺激的情况下图案化共存系统的结构，并进一步证明了其在光子学中的应用前景。这项研究表明另一类功能性软材料具有出色的自适应特性，可用于光学，电子，界面物理和化学领域。
