hardly detectable hidden chirality of saturated tertiary or chiroptical quaternary hydrocarbons, and deuterated isotopomers. In sharp contrast to the previously reported sensory systems, the chirality detection by the polyacetylene relies on an excess one-handed helix formation induced by the chiral hydrocarbons and deuterated isotopomers via significant amplification of the chirality followed by its static
我们报告了一系列手性碳氢化合物和同位素手性化合物(氘代同位素异构体)的首次直接手性传感,通过带有 2,2'-联苯酚衍生悬垂物的有规立构聚乙炔,传统的光谱方法几乎无法检测到这些。由于饱和叔烃或手性季烃和氘代同位素异构体的难以检测的隐藏手性,聚乙炔由于优先手螺旋的形成而显示出圆二色性。与之前报道的感官系统形成鲜明对比的是,聚乙炔的手性检测依赖于手性烃和氘代同位素异构体通过手性显着放大和静态记忆诱导形成的过量单手螺旋,
