本文从形状依赖性的角度，综述了分子结构与扭曲-弯曲相形成的关系。我们的结论是扭曲-弯曲相是一个普遍的现象，它发生在各种各样的材料，从二聚体到主链聚合物。在这个过程中，分子设计的化学信息实际上丢失或不相关，分子拓扑结构优先于中间相形成中的静电相互作用。作为这种宏观尺度材料的结果，仅通过形状进行工程成为可能，可能实现更多的相，并且熵是各向异性的。[图形]。
In this article, the relationship between molecular architecture and the formation of twist-bend phases is reviewed under the context of shape dependency. We conclude that the twist-bend phase is a universal phenomenon, which occurs in a wide variety of materials, for dimers through to main chain polymers. In the process, the chemical information on molecular design is effectively lost or irrelevant, and molecular topology takes precedence over electrostatic interactions in mesophase formation. As a consequence of this macro-scale material, engineering by shape alone becomes a possibility, potentially more phases may be realised, and entropy is anisotropic.[GRAPHICS].
