Charge-Transfer and Energy-Transfer Processes in D-π-A and D-π-Si-π-A dyads: Detailed Investigation on the Excited state by π–Conjugation |
| 초록 |
Donor–π–acceptor dyads (D–π–A (1) and D–π–Si–π–A (2)) were prepared to elucidate the effect of π-conjugation on photoinduced electron transfer (PET) and intramolecular charge transfer (ICT) processes,. In these molecules, triazine and carbazole moieties acted as the electron acceptor and doner, respectively. The photoluminescence of 1 red-shifted with increase of solvent polarity. In the excited state of 1, the π-conjugation acted as the linker for charge transfer (Dδ+-π-Aδ-) between the donor and acceptor moieties. The changing of a large dipole moment (Δμ=45.6 D) between the ground and excited states was determined using the Lippert-Mataga plot. In case of 2, the π-conjugation is disconnected by a Si-atom in the linker. |
