Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The facile synthesis of a tetraphenylethene‐based macrocycle having aggregation‐induced emission characteristics and that expresses illusory topology of the Penrose stairs is presented. As a result of the twisted chirality (<italic>P</italic> or <italic>M</italic>) of the tetraphenylethene unit and the axial chirality of the macrocyclic linkage (<italic>R</italic> or <italic>S</italic>), the macrocycle exhibits two absolute configurations whose interconversion is energetically favorable as revealed by theoretical calculations.</p> </abstract>
