Organic synthesis employing photoredox catalysts could accelerate chemical reactions and even enable new chemical reactions by using light to promote electrons. In the early days, the feasibility of transition metal complexes as photoredox catalysts was examined and various metal-based photoredox catalysts were reported. But, due to environmental and cost issues, organic photoredox catalysts are currently being actively studied as alternatives to transition metal photoredox catalysts. In order to develop a new photoredox catalysts, it is important to grasp the oxidation-reduction properties of the photoredox catalysts in the ground state and the excited state. However, it is still unclear how to accurately implement the excited redox potential in a quantum chemistry simulation. Therefore, research to achieve highly accurate prediction for the redox properties of photoredox catalyst is of great importance. In this study, we proposed the prediction model based on spin flip density functional theory (SF-DFT) to obtain reliable molecular structure of four dihydroquinoxalino[2,3-b]quinoxaline derivatives as well as the excited redox potential which has not been studied in detail previously. This is expected to help greatly the development of new photocatalysts in the future.
