Detailed electronic interactions between the ground and excited states in series of aryl-o-carborane compounds and intermolecular energy transfer behavior |
| 초록 |
Two different types of bis-aryl compounds were chosen to this end; one with di-phenyls and its fused fluorenyl and the other with two isomers of naphthyls, α- and β-forms. The ground state structures confirmed by the crystallographic measurements provided a close correlation of structure and electronic property. HOMO and LUMO energies were estimated and confirmed by cyclic voltammograms and DFT calculations, respectively. Excited states were calculated by the TD-DFT calculations and correlated with the corresponding absorption spectra to illustrate the electronic perturbation in a systematic fashion that excited states were found to be lowered in regard to the electronic perturbation. Final verification of the lowered energy was made from the measurement of the electron transfer efficiency between the well-studied Iridium based photosensitizer, Ir(ppy)3 and two typical bis-aryls-o-carboranes, α-Np and Ph and electron transfer efficiency of α-Np is ten times greater than that of Ph. |
