Synthesis, characterization, molecular structure, and redox properties of a new quinoidal terthiophene incorporated with a thieno[3,4-c]pyrrole moiety (5) are described. Although an electrochemical reduction of 5 formally produces the non-classical thieno[3,4-c]pyrrole moiety, 5 showed a reversible reduction wave on cyclic voltammogram, indicating that the thieno[3,4-c]pyrrole moiety can be stabilized
描述了一种新的并入噻吩并[3,4- c ]吡咯部分(5)的喹啉对噻吩的合成,表征,分子结构和氧化还原特性。尽管5的电化学还原形式会生成非经典的噻吩并[3,4- c ]吡咯部分,但5在循环伏安图上显示出可逆的还原波,表明噻吩并[3,4- c ]吡咯部分可通过以下方法稳定在5的二价阴离子状态下的离域10π共轭体系。然而,硫杂[3,4- c的掺入大大降低了还原潜能。]吡咯,与母体喹诺酮对噻吩(1)相比,阴极移动了0.4V 。
