1,9-diaryl-substituted triptycene molecules studied by Gung and coworkers. The aryl groups (Ar) are varyingly electron deficient through substitution with electron withdrawing groups. The substituents (X) on the benzyl group vary from electron donating to electron withdrawing. The interacting aromatic units assume a parallel offset conformation [26].
