Methylation of the triazole units of a π-extended, fluorescent dithieno[3,2-c:2′,3′-e]-2,7-diketophosphepin gives rise to a N,N-dimethylated species that shows considerably blue-shifted absorption and emission wavelengths, as well as two reversible and remarkably low reduction steps at Ered = −1.12 and −1.39 V that underline its improved electron-acceptor features. The observed properties are the result
的π延长,荧光灯的二噻吩并三唑单元的甲基化[3,2- c ^:2',3'- ë ] -2,7- diketophosphepin产生了N,N-二甲基化的物种,显示了显着蓝移吸收和发射波长,以及在两个可逆和相当低的还原步骤Ê红= -1.12和-1.39信息v下划线其改进电子受体的功能。所观察到的性质是通过支架的简单触发甲基大大改变电子以及结构特征的结果。
