Planar Chiral Tetrasubstituted [2.2]Paracyclophane: Optical Resolution and Functionalization

We achieved optical resolution of 4,7,12,15-tetrasubstituted [2.2]­paracyclophane and subsequent transformation to planar chiral building blocks. An optically active propeller-shaped macrocyclic compound containing a planar chiral cyclophane core was synthesized, showing excellent chiroptical properties such as high fluorescence quantum efficiency and a large circularly polarized luminescence dissymmetry factor
