索烷和轮烷是机械联锁的分子。为了进一步功能化，将此类分子引入有序流体状态是令人感兴趣的。在液晶顺序中控制它们的动态特性可能会导致新型智能软材料的开发，例如刺激响应材料和分子机器。在这篇综述中，描述了热致和溶致液晶索烷和轮烷。诱导[2]链烷和[2]轮烷液晶性的一种方法是连接介晶部分。作为介晶的刚性棒聚轮烷也表现出液晶特性。
Catenanes and rotaxanes are mechanically interlocked molecules. For further functionalization, the introduction of such molecules into ordered fluid states is of interest. The control of their dynamic properties in liquid-crystalline order may lead to the development of new smart soft materials such as stimuli-responsive materials and molecular machines. In this review, thermotropic and lyotropic liquid-crystalline catenanes and rotaxanes are described. One approach to the induction of liquid crystallinity to [2]catenanes and [2]rotaxanes is the attachment of mesogenic moieties. Rigid-rod polyrotaxanes that behave as mesogens also exhibit liquid-crystalline properties.
