Entry to coronene chemistry - Making large electron donors and acceptors

A study was conducted to demonstrate the synthesis of methoxy-substituted coronenes by paracyclophanes into coronenes using ultra-violet (UV) irradiation process. The study also performed a double Z-selective Witting reaction in dichloromethance or dimethylformamide (DMF) with the addition lithium ethanolate. The study observed that the photochemical conversion of cyclophanes to coronenes can be used to prepare new coronene-based nanographenes with different functionality and symmetry. The method can be used to obtain new donor and acceptor molecules with different electronic properties and the symmetry. The study found that the interplane distance increases with the increasing number of methoxy groups. The study also observed a decrease in the π-π interaction and an increase in solubility.
