虽然卤素键已经被认识和研究了一百多年，但直到最近，化学家们才开始应用它，并将其作为另一种超分子相互作用的可能性，用于材料的制备。本文回顾了其中一个领域，液晶，并考虑了已经成功部署的基序的例子，以产生新的中原。特别地，本文不是试图全面，而是回顾了来自特征良好的系统的关键数据，并试图首先与类似的氢键材料进行一些比较，然后考虑卤素键的不稳定性和柔韧性如何在液晶行为中表达自己。
While the halogen bond has been recognised and studied for over a hundred years, it is only in more recent times that chemists have begun to apply it and see its possibilities as another supramolecular interaction that can be deployed in the preparation of materials. This review takes one of those areas, liquid crystals, and considers examples of motifs that have been deployed successfully to generate new mesogens. In particular, rather than attempting to be comprehensive, the article reviews critically data from well‐characterised systems and seeks to first make some comparisons with analogous hydrogen‐bonded materials, before considering how the lability and flexibility of the halogen bond expresses itself in liquid crystal behaviour.
