Long-Lived Emissive Hydrogen-Bonded Macrocycles: Donors Regulating Room-Temperature Phosphorescence and Thermally Activated Delayed Fluorescence

Zecong Ye et al.

Summary: Despite the wide range of applications of macrocycles in supramolecular chemistry, achieving long-lived emissions such as room-temperature phosphorescence or thermally activated delayed fluorescence remains challenging. In this study, hydrogen-bonded macrocycles were developed, which demonstrate room-temperature phosphorescence and thermally activated delayed fluorescence through the introduction of different donors onto a rigid acceptor containing aramide skeleton. The formation of charge transfer and the presence of aromatic carbonyl groups contribute to the enhanced photoluminescence efficiency and intersystem crossing, respectively. The reduced flexibility of the chromophores in the H-bonded macrocyclic framework suppresses nonradiative decay and stabilizes triplet excitons, resulting in the acquisition of room-temperature phosphorescence and thermally activated delayed fluorescence.

A Donor-Acceptor Cage for Thermally Activated Delayed Fluorescence: toward a New Kind of TADF Exciplex Emitters

Lihua Chen et al.

Summary: We have designed an organic cage with a combination of an electron-donating triazatruxene and an electron-accepting triphenyl triazine, connected by three electronically inert pillars. This architecture allows for precise spatial separation and cofacial alignment of the two motifs, resulting in a thermally activated delayed fluorescence (TADF) macrocyclic exciplex emitter through efficient intramolecular through-space charge transfer (TSCT).

Multi-Layer π-Stacked Molecules as Efficient Thermally Activated Delayed Fluorescence Emitters

Xue-Qi Wang et al.

Summary: Multi-layer pi-stacked emitters based on spatially confined D/A/D patterns have been developed to achieve high-efficiency TADF. Dual donor moieties and a single acceptor moiety are introduced to form 3D emitters, resulting in high PLQYs, small Delta E-ST, and fast RISC processes. Devices based on these emitters exhibit maximum EQEs higher than their D/A-type analogues.
