Azulene-Embedded [n]Helicenes (n=5, 6 and 7)

Chao Duan et al.

Summary: This study successfully synthesized azulene-embedded [n]helicenes and discovered their unique physicochemical properties, such as low-lying energy state, small energy gap, and strong optical response. These [n]helicenes are of great significance for constructing a non-benzenoid helicene library and understanding the structure-property relationships.
