mono- and diacetylenic dithiafulvalenes was synthesized and employed for the construction of extended tetrathiafulvalenes (TTFs) with hexa-2,4-diyne-1,6-diylidene or deca-2,4,6,8-tetrayne-1,10-diylidene spacers between the two 1,3-dithiole rings. By stepwise acetylenic scaffolding using (E)-1,2-diethynylethene (DEE) building blocks, an extended TTF containing a total of 18 C(sp) and C(sp(2)) atoms in the
合成了单和二炔基二硫富瓦烯的选择物,并用于构建具有hexa-2,4-diyne-1,6-diylidene或deca-2,4,6,8-tetrayne-1的扩展四硫富瓦烯(TTF),两个1,3-二硫环之间的10-二亚甲基间隔基。通过使用(E)-1,2-二乙炔(DEE)结构单元的逐步炔基支架,制备了在间隔物中总共包含18个C(sp)和C(sp(2))原子的扩展TTF。还通过钯催化的交叉偶联反应,通过噻吩间隔的TTF的有效合成,建立了乙炔二硫富烯模块的多功能性。已开发的合成方案可通过三种通用方式对扩展的TTF进行功能化:1)在富马烯核上的外围取代基,2)侧基连接至间隔基的炔基部分,3)涉及炔部分的钴簇。线性和非线性光学光谱显示了扩展的TTF的强发色特性。还报道了对这些化合物的广泛电化学研究和计算,以及X射线晶体学分析。
