手性作为一个概念，在大多数长度尺度上都得到了很好的理解。然而，缺乏预测手性在长度尺度上传递效率的定量模型。我们在这里提出了一种在非手性向列液晶主体中手性纳米形状溶质的操作方法，表明可以通过异常简单的几何考虑来理解手性转移。该机制基于伪标量手性指示剂和基于每种纳米形状溶质的二维等周商的几何形状兼容性因子的乘积。该模型在一组精确设计的金纳米形状的实验组上进行了测试。这些相关纳米形状之间的计算和并行获取的实验数据库为纳米级、大分子和生物系统中手性传递的预测计算铺平了道路，从设计手性鉴别器和对映选择性催化剂到开发手性超材料和理解自然界在长度尺度上传递同手性的固有能力。手性传递效率可以通过由形状相容因子校正的伪标量手性指数来先验预测。
Chirality, as a concept, is well understood at most length scales. However, quantitative models predicting the efficacy of the transmission of chirality across length scales are lacking. We propose here a modus operandi for a chiral nanoshape solute in an achiral nematic liquid crystal host showing that that chirality transfer may be understood by unusually simple geometric considerations. This mechanism is based on the product of a pseudoscalar chirality indicator and of a geometric shape compatibility factor based on the two-dimensional isoperimetric quotients for each nanoshape solute. The model is tested on an experimental set of precisely engineered gold nanoshapes. These libraries of calculated and in-parallel acquired experimental data among related nanoshapes pave the way for predictive calculations of chirality transfer in nanoscale, macromolecular, and biological systems, from designing chiral discriminators and enantioselective catalysts to developing chiral metamaterials and understanding nature’s innate ability to transfer homochirality across length scales. Chirality transfer efficacy can be a priori predicted by a pseudoscalar chirality index corrected by a shape compatibility factor.
