摘要：
借助电子结构理论的从头算方法，研究了一类新颖的、经计算设计的、具有反转单重态-三重态（IST）能隙的三角形有机分子。所考虑的分子系统具有环状低聚物形式，其共同特征是定域于分子边缘的电子共轭。分析了选定分子从电子基态以及从最低激发单重态和三重态出发的垂直跃迁能。结果强调了在理论模型中优化激发态几何结构的重要性，以准确描述IST分子的光电性质，特别是在其应用于OLEDs方面。
英文摘要：
A novel, computationally designed, class of triangular-shape organic molecules with an inverted singlet-triplet (IST) energy gap is investigated with the aid of ab initio methods of electronic structure theory. The considered molecular systems have a form of cyclic oligomers and their common feature is electronic conjugation localized along the molecular rim. Analysis of vertical transition energies from the electronic ground state, as well as from the lowest excited singlet and triplet states of selected molecules, is conducted. The results underscore the significance of optimizing excited-state geometries in theoretical models to accurately describe the optoelectronic properties of the IST molecules, particularly in relation to their applications in OLEDs.
