Circularly Polarized Luminescence Switching in Small Organic Molecules

Abstract

The circularly polarized luminescence (CPL) switching is of significant interest for applications in security technologies and sensing devices. Small organic molecules (SOMs) show severala dvantages over metal complexes, supramolecular assemblies, and polymers. Therefore, the recent progress on the CPL switching in SOMs is here reviewed. The resultsa re summarized based on the strategies used to tune factors that influence the emission properties, and thus, to realize CPL switching. The strategies that have b…
