Experimental and theoretical study on solvent and substituent effects on the intramolecular charge transfer in 3-[(4-substituted)phenylamino]isobenzofuran-1(3H)-ones
The substituent and solvent effects on solvatochromism in 3-[(4-substituted)phenylamino]isobenzofuran-1(3 H )-ones were studied using experimental and theoretical methodologies. The effect of specific and non-specific solvent–solute interactions on the shifts of UV–Vis absorption maxima were evaluated using the Kamlet–Taft and Catalan solvent parameter sets. The experimental results were studied
使用实验和理论方法研究了取代基和溶剂对3-[(4-取代)苯基氨基]异苯并呋喃-1(3 H)-一中溶剂溶变色的影响。使用Kamlet-Taft和加泰罗尼亚语溶剂参数集评估了特定和非特定溶剂-溶质相互作用对UV-Vis吸收最大值移动的影响。用密度泛函理论(DT)和时变密度泛函理论(TD-DFT)研究了实验结果。研究了分子的HOMO / LUMO能量(E HOMO / E LUMO)和能隙(E gap)值,以及电子激发的机理和分子在基态和激发态的电子密度分布的变化。气相计算。通过TD-DFT方法在溶剂甲醇中计算电子激发。发现取代基和溶剂都影响合成分子的π电子共轭程度并影响分子内电荷转移特性。

synthesized phthalides was studied using Lamarckian genetic algorithm-based software. Results and Discussion: In the present study, we report an effective, environmentally benign scheme for the synthesis of phthalide derivatives. Compounds 5c and 5d from the current series appear to possess good anti-mycobacterial activity. dCTP: deaminasedUTPase was identified as a putative drug target in Mycobacterium. The
