Abstract
[2.2]Paracyclophane (PCP) and its derivatives have attracted growing widespread interest in recent years due to their unique chemical structures, specific photophysical properties and potential chiroptical activities, especially in the study of circularly polarized luminescence (CPL). Among the CPL‐active small organic molecules, the introduction of a PCP skeleton with planar chirality is one of the most effective strategies to obtain emitters with both high photoluminescence quantum yields (PLQYs) and luminescent dissymmetry factors (glum). At present, the development of CPL emitters based on the PCP skeleton is still limited and only a few molecular design strategies have been reported. This review summarizes and discusses the corresponding reports, and the emitters are sorted according to their chemical structures. It is expected that this review can provide researchers with a practical perspective in CPL studies and can provide inspiration for future research on CPL.
