In summary, as a proof of concept, the one-to-many strategy for realizing CP-EL is proposed based on energy and chirality transfer from short-wavelength CPL materials to long-wavelength achiral luminescent materials that are rarely used to directly produce CP-EL in previous researches. Firstly, a series of efficient near ultraviolet CPL materials with high ΦPLs and high exciton utilization based on hRISC process are explored by introducing chiral S/R-BN groups to the conjugated carbazole-phenyl-benzonitrile skeleton. The S/R-BN groups attached on benzonitrile acceptor can not only endow the molecule with CPL property but also weaken ICT effect to ensure short-wavelength emission. They can serve as light-emitting materials to fabricate highly efficient nondoped and doped near ultraviolet CP-OLEDs, providing large |gEL| values of up to 3.59 × 10 -3 and outstanding ηext,maxs of 9.0% at 404 nm (CIE = 0.166, 0.066; FWHM = 54 nm) based on S-BNPCN-o-CP and 9.1% at 420 nm (CIE = 0.155, 0.052; FWHM = 62 nm) based on S-BNPCN-o-TBCP, with very small efficiency roll-offs, demonstrating they are the most efficient near ultraviolet CP-EL materials ever reported. Secondly, no matter in solutions or in neat and doped films, the developed near ultraviolet CPL materials can successfully sensitize different kinds of achiral fluorescence, phosphorescence, TADF and MR-TADF materials to generate blue to red CP-PL signals. Thirdly, yellow-orange CP-OLEDs are successfully achieved by adopting near ultraviolet CPL materials (S/R-BNPCN-p-CP) as hosts for achiral luminescent materials, including phosphorescence emitter (Ir(tptpy)2acac), typical TADF emitter (4CzTPNBu) and MR-TADF emitter (BN3), furnishing good |gEL| values of up to 2.87 × 10 -3 and excellent ηext,maxs of 29.3%, 20.4% and 23.8%, respectively. Finally, high-performance sensitized CP-OLEDs are fabricated by using S/R-BNPCN-o-CP as sensitizer for BN3 in PPF host, which provide good |gEL| value of 1.31 × 10 -3 and outstanding ηext,max reaching 30.8% at 566 nm (FWHM = 45 nm). In view of the overlap of absorption spectra of achiral luminescent materials and the PL spectra of the near ultraviolet CPL materials, the FRET process may be accountable for the appearance of CP-PL and CP-EL signals of achiral luminescent materials. To the best of our knowledge, these CP-OLEDs with the near ultraviolet CPL materials as emitters, hosts or sensitizers are the best CP-OLEDs with apparent CP-EL signals in similar color regions reported so far. These results eloquently demonstrate the proposed one-to-many strategy for CP-EL is feasible and effective, and the robust short-wavelength CPL materials play a key role, by which different kinds of achiral luminescent material can be induced to exhibit CP-PL and CP-EL signals. This strategy could be a simple and universal approach for constructing muti-color high-performance CP-OLEDs with diverse well-developed, commercially available achiral EL materials, avoiding complicated synthetic works to create new CP-EL materials.
