In chemical science, the vertical ionization potential(VIP) is a crucial metric for understanding the electronegativity, hardness and softness of chemical material systems as well as the electronic structure and stability of molecules. Ever since the last century, the model chemistry composite methods have witnessed tremendous developments in computing the thermodynamic properties as well as the barrier heights. However, their performance in realm of the vertical electron processes of molecular systems has been rarely explored. In this study, we for the first time benchmarked the model chemistry composite methods(e.g., CBS-QB3, G4 and W1BD) in comparison with the commonly used Koopmans' s theorem(KT), electron propagator theory(e.g., OVGF, D2, P3 and P3+) and CCSD(T) methods in calculating the VIP for up to 613 molecular systems with available experimental measurements. The large-scale test calculations strongly showed that the CBS-QB3 model chemistry composite technique can be well recommended to calculate VIP from the perspectives of accuracy, economy and applicability. Notably, the VIP values of up to 7 molecules were identified to have the absolute errors of larger than 0.3 e V at all calculation levels,which have strong hints that their VIP experimental values should be re-investigated.

With the development in fabricating efficient perovskite light emitting diodes (PeLEDs), improving the operating stability becomes an urgent task. Here we report quantum dot (QD) enhanced stability of PeLEDs by introducing CdSe/ZnS core-shell QDs in toluene anti-solvent during in-situ fabrication of FAPbBr3 perovskite nanocrystals (PNCs) films. In comparison with PNC films with pristine toluene as the anti-solvent, the as-prepared FAPbBr3 PNC films with a QD monolayer on the surface exhibit improved photoluminescence quantum yield, enhanced photostability and better reproducibility. Benefiting from these advantages, the peak luminance and the maximum external quantum efficiency of the PeLED containing QD monolayer are increased from 6807 cd/m2 to 86670 cd/m2 and 2.4% to 7.1%, respectively. The T50 lifetime under the initial luminance of 1021 cd/m2 approaches 83 minutes. Based on electrical field simulation and transient electroluminescence measurements, the enhanced stability can be mainly attributed to the electrical field redistribution induced by the QD monolayer. This work demonstrates that the combination of QDs and perovskites provides an effective strategy to address the operational stability of PeLEDs. The insights into electrical field distribution effect will make great impact on stability improvement of other perovskite based devices. © 2022
