yields. The effects of different triazene substituents on optical and non-linear optical properties were investigated by means of density functional theory (DFT), in order to support design criteria. The dipole moment, HOMO-LUMO gaps, electronegativity, global chemical hardness and softness, average polarizability, first hyperpolarizability were calculated for push–pull dyes at the CAM-B3LYP/6–31++G(d
摘要 已开发出一种用于合成三氮烯取代推拉染料的短而有效的合成策略。正式的 [2 + 2] 环加成 - 逆电环化被用于制备目标推拉染料。这些原子经济的点击型化学转化发生在环境条件下,并以高产率提供了结构有趣的推拉染料。通过密度泛函理论 (DFT) 研究了不同三氮烯取代基对光学和非线性光学性质的影响,以支持设计标准。在 CAM-B3LYP/6-31++G(d,p) 理论水平计算推拉染料的偶极矩、HOMO-LUMO 间隙、电负性、整体化学硬度和柔软度、平均极化率、第一超极化率。
