specific Embodiment

[0201] 1. Transition metal complexes and their energy structures

[0202]

[0203] The energy levels of transition metal complexes can be obtained through quantum calculations, such as using TD-DFT (time-dependent density functional theory) through Gaussian03W (Gaussian Inc.). For specific simulation methods, please refer to WO2011141110. First, the semi-empirical method "Ground State / Hartree-Fock / Default Spin / LanL2MB" (Charge 0 / Spin Singlet) is used to optimize the molecular geometry, and then the energy structure of organic molecules is determined by the TD-DFT (time-dependent density functional theory) method Calculate "TD-SCF / DFT / Default Spin / B3PW91 / gen geom=connectivity pseudo=lanl2" (Charge0 / Spin Singlet). The HOMO and LUMO energy levels are calculated according to the calibration formula below, and S1 and T1 are used directly.

[0204] HOMO(eV)=((HOMO(Gaussian)×27.212)–0.9899) / 1.1206

[0205] LUMO(eV)=((LUMO(Gaussian)×27.212)–2.0041) / 1.385

[0206] Among them, HOM...
