Supramolecular Assemblies Showing Thermally Activated Delayed Fluorescence.

Supramolecular assemblies based on luminescent components offer significant advantages over their discrete counterparts, including improved quantum yields, stability, and tunability. Following interest as advanced optoelectronic materials, thermally activated delayed fluorescence (TADF) emitters are incorporated into a range of supramolecular structures. Herein, a summary of the known examples of emissive supramolecular systems that operate via a TADF mechanism with comparisons, where possible, with their discrete counterparts is presented. While the types of supramolecular structures are diverse, there are limited examples shown for each class. With the increase in photophysical performance and/or emergence of new photochemical properties upon going from molecular to supramolecular, the potential that these systems hold becomes apparent.
