Red colored CPL emission of chiral 1,2-DACH-based polymers via chiral transfer of the conjugated chain backbone structure

Four chiral polymer enantiomers were designed and synthesized. Interestingly, only R-P-1 and S-P-1 can exhibit strong mirror image Cotton effects and emit red colored circularly polarized luminescence, which can be attributed to the effective chiral transfer from the 1,2-diaminocyclohexane Schiff base to the chromophore BODIPY via the conjugated polymer chain backbone.
