A set of 12 substituted SA derivatives is considered in the present work. The choice of these substituents aims to create a push-pull system on the SA basic structure which would shade light onto its photo physics. The electronic absorption spectra of SA are recorded in the UV-VIS region, in both polar and nonpolar solvents. Assignments of the observed electronic transitions are facilitated via time-dependent
水杨基苯胺 (SA) 及其一些衍生物的电子结构通过实验和理论进行了研究。所研究化合物的平衡几何结构在 B3LYP/6-311++G** 理论水平确定。在目前的工作中考虑了一组 12 种取代的 SA 衍生物。这些取代基的选择旨在在 SA 基本结构上创建一个推拉系统,该系统将光线遮蔽到其光物理上。SA 的电子吸收光谱记录在 UV-VIS 区域,在极性和非极性溶剂中。通过在同一理论水平上的时间相关密度泛函理论 (TDDFT) 计算来促进观察到的电子跃迁的分配。确定了对每个激发态有贡献的电子配置,并表征了相关的 MO。根据自然键轨道 (NBO) 分析和供体和受体 MO 之间的二阶扰动相互作用来估计和讨论离域和分子内电荷转移的程度。根据基态和激发态极化率的差异讨论了溶剂对电子吸收光谱的影响。SA 及其衍生物的 FTIR 光谱是在 KBr 血小板中测量的。基于计算出的势能分布给出了详细的振动分配。识别表征

based on novel copper(II) complexes were synthesized and obtained by the reaction of substituent salicylaldehyde with amine derivatives, and then reacted with Cu(CH3COO)2·H2O, respectively. Investigation on the interference from other species suggested that copper(II) complexes have high selectivity for HS− over other anions (AcO−, , F−, Cl−, Br− and I−), followed by the release of the copper ion to give
