We have developed a two- or three-step synthesis of polyaza[5]-[9]helicenes by consecutive N-H/C-H coupling with a hypervalent iodine reagent. We further evaluated their photophysical properties, and circularly polarized luminescence properties and found that g_lum values increase with the number of fused rings up to 2.7 × 10^-2, which is the highest value among [9]helicenes.
