Star-shaped conjugated oligomer T3HTP containing pyrene, 3-hexylthiophene and triphenylamine, has been successfully synthesized via a simple one-pot sequential direct arylation process. The chemical structure and optical properties of T3HTP oligomer were characterized via proton nuclear magnetic resonance (¹H-NMR), UV–vis and fluorescence spectroscopies. The results indicated that T3HTP oligomer showed good fluorescence quenching toward TNT, which is useful for identifying explosive nitro aromatic compounds.

基于3-己基噻吩，pyr和三苯胺的一锅合成星形共轭低聚物作为TNT化学传感器

已通过简单的一锅顺序直接芳基化方法成功合成了含有pyr，3-己基噻吩和三苯胺的星形共轭低聚物T3HTP。T3HTP低聚物的化学结构和光学性质通过质子核磁共振（¹ H-NMR），紫外可见光谱和荧光光谱进行表征。结果表明，T3HTP低聚物对TNT表现出良好的荧光猝灭作用，可用于鉴定爆炸性硝基芳族化合物。
