(Invited) Synthesis and Property of Carbazole-Based Porphyrins

As carbazole is benzene-fused pyrrole, incorporation of a carbazole unit into fused porphyrinoids represents interesting possibilities. We have developed carbazole-based porphyrins which exhibited distinct aromaticity and strong NIR absorption due to the quadruple benzo-fusion moieties. Following the successful synthesis, we have investigated the peripheral and core modifications and ring-expansion of the macrocycle as well as the applications to BODIPY derivatives. Here synthesis and property of these carbazole-based porphyrins are reported. Figure 1
