A new and efficient two‐step procedure for the preparation of 5,7‐disubstituted 5,7‐dihydropyrido[2,3‐ b :6,5‐ b ′]diindoles, containing aryl‐, benzyl‐ as well as alkyl‐substituents has been developed. This methodology consists of a chemo‐selective double Suzuki‐Miyaura cross‐coupling reaction followed by a fourfold Buchwald‐Hartwig amination reaction. UV/VIS absorption and fluorescence measurements have been carried out for a selected series of compounds. The results are summarized and compared with those of the isomeric 5,7‐disubstituted 5‐7‐dihydropyrido[3,2‐ b :5,6‐ b ′]diindoles.
