dependence of optical limiting properties on molecular structures, especially the strong intermolecular influence, such as the influences of hydrogen bond, dipole–dipole interaction and their synergetic effect on optical limiting properties, three polar D–π–A conjugated quinoline-based heterocyclic azo derivatives (3a, 3b and 3c) with different hydrogen-bond recognition abilities were designed and synthesized
为了进一步研究光学极限性质对分子结构的依赖性,尤其是强烈的分子间影响,例如氢键,偶极-偶极相互作用及其对光学极限性质的协同效应,三极性D–π–A共轭喹啉-基于杂环的偶氮衍生物(3a,3b和3c)设计并合成了具有不同氢键识别能力的)。通过红外光谱,热重分析和紫外可见光谱对它们的结构和性质进行了表征和评估。基于理论计算和氢键协同作用及偶极-偶极相互作用的分子组装实验结果,详细研究了光极限性质的增强机理。结果表明,这些极性D–π–A共轭光学材料的光学极限性质受到分子结构,强分子间相互作用及其协同增强作用的显着影响。
