含有手性亚砜的o-OPE与金属阳离子的亲氧作用调控CPL圆偏振发光

OFF/ON switching of circularly polarized luminescence by oxophilic interaction of homochiral sulfoxide-containing o-OPEs with metal cations

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.
