Embodiment 3

[0202] Embodiment 3, the energy structure of organic compound

[0203] The energy levels of organic materials 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 / Semi-empirical / Default Spin / AM1" (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" and the basis set "6-31G(d)" (Charge 0 / 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(G)×27.212)-0.9899) / 1.1206

[0205] LUMO(eV)=((LUMO(G)×27.212)-2.0041) / 1.385

[0206] Among them, HOMO(G) and LUMO(G) are the direct calculation r...

Description

technical field [0001] The invention relates to the field of novel organic photoelectric materials, in particular to a class of spirocyclic derivatives, high polymers, mixtures, compositions and organic electronic devices containing them. Background technique [0002] Organic semiconductor materials have great potential for applications in optoelectronic devices such as light-emitting diodes (OLEDs), such as flat panel displays and lighting, due to their structural diversity, relatively low fabrication cost, and superior optoelectronic performance. [0003] In order to improve the light-emitting performance of organic light-emitting diodes and promote the large-scale industrialization process of organic light-emitting diodes, various organic photoelectric performance material systems have been widely developed. However, the performance of OLED, especially the lifetime, still needs to be improved. Such as phosphorescent OLED, the stability of its host material determines the...
