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

$\"\"$ <\/p>\n

\n

Here we describe a new class of CPL<\/a> switches based on oxophilic interactions between chiral sulfoxide-containing\u00a0ortho<\/em>-phenylene ethynylene (o<\/em>-OPE) foldamers and cationic metals. These systems represent a unique case combining high\u00a0g<\/em>_{lum<\/sub><\/small>\u00a0values (up to 0.7 \u00d7 10^{\u22122<\/sup><\/small>) and high quantum yields in both folded ON and unfolded OFF CPL states.<\/p>\n}}
