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 g lum values (up to 0.7 × 10 −2 ) and high quantum yields in both...

Description
Summary: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 g lum values (up to 0.7 × 10 −2 ) and high quantum yields in both folded ON and unfolded OFF CPL states. CPL switches with high g lum and Φ are described.
