The design, synthesis and evaluation of the amplified spontaneous emission (ASE) properties of a series of arylalkynyl-benzo[c][1,2,5]thiadiazole (BTD) and [1,2,5]thiadiazolo[3,4-g]quinoxaline (TDQ) derivatives are described. The synthetic strategy entailed the use of Sonogashira and Stille reactions based on the different aromatic natures of the two cores. The ASE properties were measured in thin
一系列芳基炔基-苯并[ c ] [1,2,5]噻二唑(BTD)和[1,2,5]噻二唑[3,4-]的放大自发发射(ASE)性质的设计,合成和评估G描述了喹喔啉(TDQ)衍生物。合成策略需要根据两个核的不同芳族性质使用Sonogashira和Stille反应。在掺杂有不同浓度的合成化合物的聚苯乙烯(PS)薄膜中测量了ASE性能。BTD衍生物显示出光致发光光谱(PL)变窄,因此揭示了其潜在的激光应用。只有一种TDQ衍生物显示ASE。进行了X射线衍射分析,以了解观察到的结果并建立结构与属性之间的关系。显示强分子堆积的分子淬灭了PL发射,因此产生了更高的ASE阈值。
