• University of Technology (Shandong Academy of Sciences), Jinan, 250014, China 10.3762/bjoc.17.6 Abstract The Tröger's base derivative rac-TBPP was synthesized and separated into two enantiomers R2N-TBPP and S2N-TBPP by chiral column chromatography. These compounds show a strong circularly polarized

• ; inversion of CPL handedness; Tröger's base; Introduction Recently, much effort has been devoted to constructing luminescent materials with efficient high emission in the solid state [1][2][3]. More and more types of fluorophores with aggregation-induced emission (AIE) characteristics have been discovered

• construct CPL-active materials [19][20][21], so the fluorescent Tröger's base derivatives rac-TBPP fall into our sight as the candidate to construct CPL-active materials. Herein, we take two stratgies to construct rac-TBPP-based CPL material. One stratgy is to separate non-CPL emission rac-TBPP into CPL

• . Scheme 5 summarizes the coordination behavior of the two ligands 1 and 2 and their mixture towards copper(I) ions. Conclusion In summary, we have synthesized two concave or V-shaped multivalent ligands − a dissymmetric bis(phenanthroline) ligand (rac)-1 based on the Tröger's base scaffold in its racemic
