“…In 2022, Hatakeyama and co-workers reported a MR-TADF, V-DABNA-Mes [54], with the π-extended helicene structure containing the multiple boron atoms. Owing to the efficient MR effect of three boron and six nitrogen atoms (figure 2), the compound exhibited the narrowband sky-blue emission with a λ PL at 486 nm, an FWHM PL of 16 nm, and a Φ PL of 79% in toluene.…”

Multi-resonance (MR) materials have attracted considerable attention owing to their ability to achieve high color purity emissions with the small full-width at half-maxima (FWHMs) in organic light-emitting diodes (OLEDs), which is crucial for wide color-gamut displays. Nowadays, MR emitters covering almost full colorst have been developed and applied to construct high-performance narrowband OLEDs. From the commercial perspective of device fabrication, compared with the vacuum-deposition technique, solution processes provide the more economical approaches for the production of low-cost and large-area OLED display panels. Since the device performances of solution-processed MR-OLEDs still lag behind those of vacuum-deposited devices, developing MR emitters featuring intrinsicaly narrow FWHMs, fast reverse intersystem crossing rate, and good solubility are urgently needed in future cost-effective ultrahigh-definition (UHD) displays. In this focus review, we summarize the recent advances in solution-processable MR-type emitters, especially for the thermally activated delayed fluorescence (TADF) molecules. Molecular design, photophysical properties, and solution-processed device performances are correlated. Additionally, the challenges in solution-processed MR-OLEDs and the promising applications of efficient solution-processable MR emitters are also envisaged.
