| 英文摘要 | We report a highly efficient synthetic methodology toward tri-n-annulated hexarylenes from easily available n-annulated perylenes, which is favored by the oxidative ring fusion driven by ddq/sc(otf)(3). to assist the characterization of the new compounds, quantum-chemical calculations of structural and spectroscopic properties have been carried out for three oligomers of n-annulated rylenes. it is shown that tri-n-annulated hexarylene dyes display remarkably large dipole moments likely associated with the formation of h aggregates, as suggested by the marked concentration dependence of the measured uv vis spectra. it is suggested that the combination of pi-pi stacking interactions and dipole dipole interactions may favor the formation of highly ordered supramolecular structures, resulting in enhanced charge carrier mobilities. |
