A new multi-sensor material based on helical copolymers showing the chiral conflict effect have been prepared. It can successfully detect and identify diverse metal cations in solution. The design of this material has taken into account not only the opposite helical senses induced by the two chiral monomers in the copolymer, but also their dynamic behavior. The induced helical sense can thus be enhanced
制备了一种新的基于螺旋共聚物的多传感器材料,该材料显示出手性冲突效应。它可以成功地检测和识别溶液中的多种金属阳离子。这种材料的设计不仅考虑了共聚物中两种手性单体引起的相反螺旋感,还考虑了它们的动力学行为。因此,可以通过与不同刺激(即金属离子)的相互作用来增强,减少或反转感应的螺旋感。因此,取决于共聚物的组成(例如单体比例和绝对构型)以及金属离子的性质,这些动态螺旋共聚物采用单手P或M螺旋的响应是独特的,这不仅使它成为可能。不仅可以检测它们的存在,还可以分别识别它们。
