Carbazole-based BODIPYs were synthesized in three steps using an organometallic approach consisting of sequential Ir-catalyzed borylation, Suzuki–Miyaura coupling, and boron complexation. Various substituents introduced into the carbazole moiety, large substituent effects confirmed by means absorption spectroscopy, cyclic voltammetry, DFT calculations. Dibenzocarbazoles also converted corresponding BODIPYs.
