Abstract

AbstractThe newly synthesized chiral active [5]helicene‐like tetrabenzofluorene (TBF) based highly red‐emitting molecules exhibit flower‐like self‐assembly. These molecules display photophysical and structural properties such as intramolecular charge transfer, dual state emission, large fluorescence quantum yield, and solvatochromism. In TBFID, the indandione functional group attached on both sides as the terminal group offers an A‐D‐A push‐pull effect and acts as a strong acceptor to cause more redshift in solution as well as in solid state as compared to TBFPA (TBF with benzaldehyde functional group in terminal position). The self‐assembly studies of TBFID demonstrate the aggregation‐induced emission enhancement (AIEE) attributed to the restriction of intramolecular rotation at the aggregated state. Furthermore, TBFID shows high quantum yield and intense red emission, making the molecule fit for organic light‐emitting diodes (OLED) and bioimaging applications.
