Tetrabenzotriazacorrole (TBC) complexes are tetrapyrrolic aromatic corrole macrocycles, which are phthalocyanine (Pc)-like and are new members of the porphyrin family. A TBC molecule is a chemically reduced Pc. Because of their distinct structural, electronic and UV–vis spectroscopic features, and electrochemical behavior, TBCs have many potential applications. This paper reviews the latest synthesis, characterization, properties, and applications of TBC compounds. The opportunities for further research on TBCs are also discussed.
