Abstract
Here we describe a new class of CPL switches based on oxophilic interactions between chiral sulfoxide-containing ortho-phenylene ethynylene (o-OPE) foldamers and cationic metals. These systems represent a unique case combining high glum values (up to 0.7 × 10-2) and high quantum yields in both folded ON and unfolded OFF CPL states.
摘要
在这里，我们描述了一类基于手性砜含邻苯二乙炔（o-OPE）折叠体与阳离子金属之间亲氧相互作用的新型 CPL 开关。这些体系代表了一种独特的情况，即结合了高的扭转值（高达 0.7×10-2）和折叠的 ON 状态和展开的 OFF CPL 状态下的高量子产率。
