Key Points

This research aims to explore the relationship between the spin dynamics of charge-separated states and excited singlet states in radical pair systems.
Investigated thermally assisted delayed fluorescence (TADF) in electron-donor-bridge-acceptor triads
Analyzed the spin dynamics associated with charge-separated states under various conditions
Assessed the performance through experimental and theoretical approaches
Demonstrated the coupling of radical pair spin dynamics to excited singlet states
Revealed that this coupling enhances the observability of spin dynamics in charge-separated states
Showed that the approach can lead to improved understanding of TADF mechanisms

Implication

Observes spin dynamics of charge-separated states in radical pair systems, suggesting new insights into TADF mechanisms.

Abstract

Thermally assisted delayed fluorescence (TADF) in electron–donor–bridge–acceptor triads has recently been shown to provide a new way of observing the spin dynamics of charge-separated states (CSS) corresponding to linked radical...
