“…Since the effects of carbazole groups on the chemical, physical, and optical properties of phthalocyanines have been rarely studied, our group has been interested in research on scientific features of novel carbazole-containing phthalocyanines in recent years. [37][38][39][40] Carbazoles include an aromatic nitrogen-containing tricyclic structure and exhibit high charge transfer, environmental resistance, chemical stability, and ease of functionalization, which make them efficient agents for many applications. 41 Recently, their potential utility in electrochromic rechargeable batteries has been investigated owing to their excellent electrochromic and photoconductive properties.…”
