在喹吖啶酮结构的基础上,设计合成了一系列具有推拉电子结构且含二氢喹啉酮结构的化合物,并研究了结构改变和不同溶剂对吸收光谱和荧光光谱的影响.研究发现化合物中增大的共轭体系和增强的推拉电子基团会导致吸收峰和荧光峰产生大的红移;随着结构的改变,这些化合物的荧光从蓝色变成橙红色.这些化合物随着溶剂极性的增加,吸收峰和荧光峰都表现出强烈的红移.并进一步研究了这类荧光化合物的分子内电荷转移现象.它们作为一类新的荧光化合物在电致发光领域有潜在的应用价值.
Based on the structure of quinacridone, a series of compounds containing dihydronequinolone with push-pull electronic structure were designed and synthesized, and the effects of structural change and different solvents on absorption and fluorescence spectra were studied. It was found that compound The increased conjugated system and the enhanced push-pull electron groups cause a large red shift of the absorption and fluorescence peaks, and the fluorescence of these compounds changes from blue to orange-red as the structure changes.These compounds, as the solvent The increase of the polarity, the absorption peak and the fluorescence peak all show a strong redshift, and the intramolecular charge transfer phenomena of these fluorescent compounds have been further studied.They have potential application as a new fluorescent compound in the field of electroluminescence value.
