Site-selective nitrogen insertion in double helicenes and dibenzo-terrylenes

Polycyclic aromatic hydrocarbons, particularly light-absorbing and light-emitting rylenes, are central to optoelectronic devices, sensors, displays and bioimaging, yet small structural changes can strongly alter their performance. A key challenge is to place heteroatoms at chosen positions in large aromatic framework...
