  • Synthesis and photophysical properties of new functionalized coronene molecules

説明

Coronene is the smallest homologue of benzene with six-fold symmetry, giving it a unique electronic structure due to the perfect delocalization of aromaticity between the six outer rings. The representative way to use is hole-transporting or light-emitting material in organic devices. Coronene based molecules can also form supramolecular aggregates due to the characteristic columnar formation. However, functionalized coronenes are very rare because of synthetic labor, so far. Therefore, methoxy-substituted coronenes were synthesized by the Wittig reaction of dimethoxyterephthalic dialdehyde with 1,4-xylene-bis-triphenylphosphoniumbromide followed by the McMurry coupling gives the paracyclophanes. UV irradiation of paracyclophanes gives the corresponding methoxy-substituted coronones which on treatment with BBr3 gives the hydroxy-substituted coronenes. The photophysical and structural properties such as absorption, fluorescence, TEM etc in these molecules were studied extensively. Salient features of these results will be presented.
