The study focuses on purely organic molecules that emit light by dual emissive pathways, emphasizing the importance of understanding the relationship between molecular structure and photophysical processes. Categorizing types of dual emissive based on spin multiplicity and emission time range, recent experimental advances and design rules for novel candidates are outlined, providing opportunities for new materials synthesis and future innovations in this area.
Purely organic molecules, which emit light by dual emissive (DE) pathways, have received increased attention in the last decade. These materials are now being utilized in practical optoelectronic, sensing and biomedical applications. In order to further extend the application of the DE emitters, it is crucial to gain a fundamental understanding of the links between the molecular structure and the underlying photophysical processes. This review categorizes the types of DE according to the spin multiplicity and time range of the emission, with emphasis on recent experimental advances. The design rules towards novel DE molecular candidates, the most perspective types of DE and possible future applications are outlined. These exciting developments highlight the opportunities for new materials synthesis and pave the way for accelerated future innovation and developments in this area.
