Diodes électroluminescentes hybrides blanches à base de complexes Cu(I) et de MOF Matériaux hybrides
Current white light-emitting diodes (WLEDs) are based on inorganic phosphors, such as CdQDs or rare earth elements. Those are toxic and/or scarce and therefore are considered as a critical aspect towards the sustainable development and use of the WLED technology. Hybrid WLEDs (HWLEDs) based on organic phosphors (OPs), such as coordination complexes, conjugated polymers, laser dyes, etc., are considered as an alternative if the stability and efficiency requirements are met. In this context, OPs based on emitting Ir(III) complexes have recently reached the desired device performance, but they are also considered as scarce material. CuMOF-LED proposes the development of new sustainable, non-toxic, and highly emissive OPs based on Cu(I) complexes-metal organic framework hybrid materials for next generation HWLEDs. Here, highly emissive blueish green Cu(I) complexes will be inserted in highly emissive yellowish orange Zn(II) or Zr(IV) MOFs, leading to a stable host-guest system prepared by either physical diffusion or chemical bonding. Both the host and the guest will be designed to reach high efficiencies and will be in synergy to stabilize each other. These hybrid OPs will be used for the implementation of highly performing HWLEDs, targeting features such as CIE coordinates close to 0.31; 0.31, CRI >90, efficiency >100 lm/W, and color efficiency over 100-500h under mid-power excitations. This multidisciplinary proposal covers a wide range of different fields of science, i.e. organic/coordination chemistry, material science, photophysics, coating fabrication, photo and thermal stability studies, and fabrication/analysis of lighting devices (HWLEDs). CuMOF-LED will open-up new horizons on the field of optoelectronics, with the implementation of sustainable OPs in HLEDs.
