- Abstract:
- A series of donor-π-acceptor(D-π-A)compounds involving varied donors and acceptors as well as a dihydroquinolinone moiety were synthesized.Tuned fluorescent colors from blue to orange were successfully realized in them.Spectroscopic analysis exhibits that the increased conjugated system, enhanced electron-donating ability of acceptor, and electron-withdrawing ability of donor result in red shift in both absorption and fluorescence for these compounds.Both the absorption and fluorescence show strong bathochromic shift effect with the increase in the polarity of solvents.It indicates that they are intramolecular charge transfer(ICT)fluorescent compounds and may have potential application as novel electroluminescent material.
- 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.
