中文摘要：

设计合成了4种基于10-甲氧基亚氨基芪的D-π-A-π-A型共轭小分子,并通过核磁共振氢谱、碳谱和飞行时间质谱确证了它们的分子结构。通过热失重分析（TGA）、紫外分光光度计（UV-Vis）和循环伏安法（CV）研究了这4种D-π-A-π-A分子的光物理性能;初步探索了分子中给体单元的大小和末端受体单元的结构对分子光物理性能的影响。该研究为设计新型的D-π-A-π-A型共轭小分子有机光电材料具有一定的意义。

英文摘要：

FourD-π-A-π-A conjugated molecules based on 10-methoxy-5H-dibenzo[b,f]azepine unit were designed and prepared in this context.The molecular structures were confirmed by 1 H NMR,13 C NMR and TOF-MS.Furthermore,the photophysical properties of these molecules were investigated through TGA,UV-Vis and CV measurements.The effect of donor size and terminal acceptor unit in these molecules on their photophysical property were explored.This research has certain scientific significance for design novel organic optoelectronic materials with D-π-A-π-A feature.
