[7]Helicene-like
compounds with a fluorene unit were successfully
synthesized using a platinum-catalyzed double cyclization reaction.
Crystal structures and photophysical properties of these compounds
were also studied. In particular, they were found to exhibit a high
fluorescence quantum yield and a relatively large g value (dissymmetric factor) of circularly polarized luminescence
(CPL) for small molecules.
