has been less investigated compared with the rich synthetic chemistry of porphyrin
and its analogues. However, considering that Pc and SubPc exhibit intense Q band
in the UV/vis region, it is reasonable to use these structures to design new functional chromophores. From this viewpoint, several synthetic investigations have been
performed, including the author’s contribution to this research field (Shimizu and
Kobayashi 2014). Although the synthetic methods have still been limited, the accumulation of knowledge will lead to a new phase of synthetic chemistry of Pc and
related analogues, the glimpse of which can be seen in the recent synthetic achievements of PBTAS and carbazosubphthalocyanine. The author hopes this book chapter
may become a future guide to develop new Pc-based functional chromophores.
