Description
Summary:Circularly polarized luminescence (CPL) has attracted much interest due to its potential applications on chiral photonic techniques and optoelectronic materials science. As known, dissymmetry factor (gem) of CPL is one essential factor for evaluating the features of CPL‐active materials. Much attention has focused on how to increase the gem value, which is one of the most important issues for CPL practical applications. Recently, more and more works have demonstrated that chiral supramolecular could provide the significant strategy to improve the gem value through the orderly helical superstructure of chiral building blocks. Normally, this kind of chiral supramolecular assembly process can be accompanied by chirality transfer and induction mechanism, which can promote the amplification effect on the induced CPL of achiral dyes. In this review, we fully summarized recent advances on the induced CPL‐active materials of chiral supramolecular co‐assemblies, their applications in circularly polarized organic light‐emitting diodes (CP‐OLEDs) and current challenges. Chiral supramolecular assembly processes can be accompanied by chirality transfer and induction mechanism, which can promote the amplification effect on the induced CPL of achiral dyes. This review summarizes the related advances on the induced CPL‐active materials of chiral co‐assembly system, their research status and application prospects in CP‐EL field, and current challenges.
