this manuscript we wish to report our results on construction of polycyclic aromatic hydrocarbon (PAH, PAH = 9-antracenyl, 1-pyrenyl)-based bola-type fluorophores/chemosensors via an unusual Clemmensen reduction of the corresponding penta-1,4-dien-3-ones. In aqueous solutions the thus obtained bola-type molecules demonstrate intensive excimer emission at 500 nm, as well as well-pronounced “turn-off”
Bola 型有机支架对于在各种领域的应用至关重要。在这份手稿中,我们希望报告我们通过相应五 1,4- 的不寻常克莱门森还原来构建基于多环芳烃 (PAH, PAH = 9-antracenyl, 1-pyrenyl) 的 bola 型荧光团/化学传感器的结果dien-3-ones。在水溶液中,由此获得的 bola 型分子在 500 nm 处表现出强烈的准分子发射,以及对常见硝基爆炸性成分(如 2,4-二硝基甲苯 (DNT) 和 2 ,4,6-三硝基甲苯 (TNT) 以及难以检测的四硝酸季戊四醇酯 (PETN)。
