CPL emission of chiral BINOL-based polymers via chiral transfer of the conjugated chain backbone structure†
Abstract
Two chiral BINOL-based polymer enantiomers R-P and S-P incorporating phenothiazine moieties in the main chain backbone can exhibit mirror image Cotton effects and emit green color circularly polarized luminescence (CPL), which can be attributed to chiral transfer of binaphthyl to chromophore phenothiazine moieties via the conjugated polymer chain backbone.
