在这里,我们介绍π共轭有机结构单元8-溴吲哚[2,3- b ]喹喔啉(indoloquinoxaline,IQ),它结合了吸电子和供体氮原子。它可以通过直接且高产率的缩合反应从低成本的起始原料中获得。在材料设计方面,吲哚喹喔啉适合用作终端单元;它可以作为π共轭体系的平面延伸,并容易被脂族侧链官能化,这可以改变材料的溶解度和自组装过程。吲哚喹喔啉骨架具有高度的通用性,考虑到数百种市售的吲哚和苯二胺原料,可以很容易地衍生化。在这种情况下,吲哚喹喔啉的结构单元既不富电子也不缺乏电子,这使得材料的光电性能在很大程度上取决于分子核的特性,
Abstract The reaction of different substituted isatins with ortho-phenylenediamine in acetic acid has been investigated. While electron-donor substituents on isatin shift the reaction toward classical 6H-indolo[2,3-b]quinoxaline ring closure, electron-withdrawing groups enhance the formation of 3-(2′-amino-5′-substituted)-quinoxaline-2(1H)-ones. The structures of all synthesized compounds were assigned
