Room-temperature observation for reverse intersystem crossing (RISC) from triplet to singlet charge-transfer states (CT3 → CT1) and clarification of its phys. mechanisms are the key requirements for designing highly efficient exciplex-based organic light-emitting diodes (OLEDs). Herein, balanced and unbalanced exciplex-based OLEDs were fabricated by employing different hole-injection layers, and RISC of CT states was directly observed via analyzing magneto-conductance (MC) and magneto-electroluminescence (MEL) traces of the balanced device at room temperature Specifically, current-dependent MC traces of the balanced device always present B-mediated RISC features, whereas those from the unbalanced one depict the superposition of B-mediated intersystem crossing (ISC) and the dissociation of CT3 by excessive charge carriers. Simultaneously, MEL curves of the balanced device display the conversion from ISC to RISC with lowering bias current, but those from the unbalanced one always show ISC under all of bias currents. Moreover, although all of current-dependent magneto-efficiency (Mη) traces exhibit ISC, Mη values are ~2 times lower in the balanced device than the unbalanced one. These rich changes of magnetic-field responses demonstrate that balanced carrier injection can facilitate the occurrence of RISC by reducing the dissociation of CT3. Expectedly, the current efficiency of electroluminescence from the balanced device is increased by ~2.2 times, which originates from the improvement of delayed luminescence because of the enhanced RISC. Accordingly, this work not only clarifies the prerequisite for observing RISC of CT states but also provides strategies for designing high-efficiency exciplex-based OLEDs.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Thermally stable inverted organic light-emitting diodes using Ag-doped 4,7-diphenyl-1,10-phenanthroline as an electron injection layer, published in 2021-12-31, which mentions a compound: 2085-33-8, mainly applied to silver organic light emitting diode annealing thermal stability, Computed Properties of C27H18AlN3O3.

The thermal stability of organic functional materials affects the performance and lifetime of organic light-emitting diodes (OLEDs). We have developed a thermally stable inverted OLEDs (IOLEDs) by employing silver (Ag) doped into 4,7-diphenyl-1,10-phenanthroline (Bphen) as an n-type doped electron injection layer (EIL). We found that the formation of Ag complexes by coordination reaction could enhance the thermal stability and produce an asym. diffraction pattern based on an anal. of grazing incidence small angle X-ray scattering. Interestingly, with the annealing temperature increasing to 100°C, the elec. properties of electron-only cells show differentiated phenomenon that the c.d. based on Ag dopant remains basically unchanged, which is opposite to Cs2CO3 dopant. In addition, at the high temperature of 100°C, the IOLEDs with Cs2CO3 doped Bphen as an EIL was damaged completely, while the Ag dopant-based devices still maintained good photoelec. characteristics. Finally, we have demonstrated that the optimized IOLEDs achieved a 40.3% enhancement in current efficiency compared to the conventional device. This work provides a new strategy to increase the thermal stability and performance for the application of IOLEDs operated under high temperature

The understanding of the Physics underlying the performances of spin-valve devices comprising organic semiconductors is still incomplete. According to some recent models, spin transport takes place in an impurity band inside the fundamental gap of the organic semiconductor. This seems to be confirmed by recent experiments performed with La0.7Sr0.3MnO3/Alq3/AlOx/Co devices. The reported results suggest a possible correlation between the magnetoresistance and the variable oxygen doping in the Alq3 spacer. In this paper we investigate the electronic and magnetic properties of O2 mols. and ions in Alq3 films by means of first-principles calculations to establish whether oxygen plays any important role for spin transport in La0.7Sr0.3MnO3/Alq3/AlOx/Co devices. The conclusion is that it does not. In fact, we show that O2 mols. do not form an impurity band and there is no magnetic interaction between them. In contrast, we suggest that spin-transport may be enabled by the direct exchange coupling between Alq-3 ions.

Metal-organic frameworks (MOFs) based on 0-D Zn halide secondary building units (SBUs), which emit large Stokes shifted broadband bluish-white light, are reported. The broadband emission probably originates from self-trapped excitons, owing to the structurally deformable SBUs. Among the intrinsic self-trapped emitters, these MOFs are rare examples that exhibit both long-term environmental stability and contain nontoxic elements. The open porosity enables the MOF to serve as a host matrix for encapsulating green-emitting Alq3 mols., exhibiting cold white-light chromatic coordinates of (0.27,0.36) and a correlated color temperature of 8321 K.
