Tröger's base derivative rac-TBPP was synthesized and separated into two enantiomers R2N-TBPP and S2N-TBPP by chiral column, which emit strong circularly polarized luminescence with glum values of +0.0021, and –0.0025, respectively. The different way to fabricate the CPL-active material is to cogel the fluorescent rac-TBPP with a chiral D-glutamic acid gelator DGG by co-assembly strategies. At the molar ratio of rac-TBPP : DGG = 1 : 80, the glum value of the cogel was increased to be about three times higher than that observed from R2N-TBPP and S2N-TBPP enantiomers. Interestingly, the CPL handedness of the rac-TBPP/DGG cogel could be adjusted effectively by changing their stoichiometric ratios.

Keywords: Tröger's base; circularly polarized luminescence; chiral resolution; co-gelation; inversion of CPL handedness
