Two families of thiophene-based 2-arylpyridines, in which aryl is phenyl and 2,4-difluorophenyl, have been developed. The pyridine ring of the new compounds is substituted at the 4-position with π-conjugated electron-rich and electron-poor thiophene-based fragments to tune the optical and energetic properties. The high-yielding synthetic access, which consists of two sequential Suzuki coupling reactions
已经开发了两个基于噻吩的 2-芳基吡啶,其中芳基是苯基和 2,4-二氟苯基。新化合物的吡啶环在 4 位被 π 共轭富电子和缺电子噻吩基片段取代,以调整光学和能量特性。高产合成通路由两个连续的 Suzuki 偶联反应组成,第一个是完全区域选择性的,具有广泛的适用性,并允许获得多种衍生物。已经研究了吸收/发射和氧化还原特性,以及 HOMO 和 LUMO 能级;结果表明,光学和电子特性可以在很宽的范围内进行调整。
