bridged by an allene framework (1) was synthesized. An X-ray analysis of 1 revealed an effective conjugation between TTF and the allene backbone. Allene 1 was resolved into both enantiomers, which showed strong chiroptical electrochromic properties. Absolute configuration of the allene was validated by theoretical study of the electronic circular dichroism (ECD) spectrum. ECD spectra of cationic species
合成了由丙二烯骨架(1)桥接的手性四硫富瓦烯(TTF)二聚体。X射线分析显示1为TTF与丙二烯骨架之间的有效共轭。将丙二烯1拆分为两种对映体,均显示出很强的手性电致变色特性。通过电子圆二色性(ECD)光谱的理论研究验证了丙二烯的绝对构型。阳离子物质1 2+和1 4+的ECD光谱在可见光区域表现出强烈的棉花效应。
