Chiral-bridged triarylamines are a class of electroactive heterohelicences, which form stable helical structures for electronic and optical applications. Recently, they have been utilized as probes for circularly polarized luminescence (CPL) and single molecule chiroptical studies. However, selective functionalization of chiral-bridged triarylamines in order to widen the scope of the probes that can be utilized for chiroptical studies remains a challenge due to the symmetry of the molecules. In this poster we will describe the synthesis, structure and resolution of apically functionalized chiral-bridged triarylamines (M  -1  /P  -1  ) utilizing regioselective copper catalyzed amination. Furthermore, synthesis of novel chiral-bridged triarylamine dimers (M  -2  /P  -2  ) starting from M  -1  and P  -1   will also be described.
