| 英文摘要 | Six triarylamine derivatives 1-6 with branched multi-pyridine substituents were prepared and characterized. These compounds are distinguished by the substituent on one of the phenyl group with NO2 for 1, CN for 2, Cl for 3, p-C6H4OMe for 4, OMe for 5, and NMe2 for 6, respectively. As revealed by single crystal X-ray analysis, these substituents play an important role in determining the configuration of the triarylamine framework and the crystal packing of 1-6. The emission properties of these compounds were examined in different solvents (toluene, CH2Cl2, acetone, tetrahydrofuran (THF), and N,N-dimethylformamide (DMF)) and in solid states. Distinct dual emissions from the localized emissive state and the intramolecular charge transfer state were observed for compound 5 in CH2Cl2. Compounds 1 and 6 show apparent aggregated enhanced emissions in acetone/H2O. The emission properties of these compounds were further modulated by the addition of tris(pentafluorophenyl)borane. In addition, density functional theory (DFT) and time-dependent DFT (TDDFT) calculations have been performed on the ground and singlet excited states to complement the experimental findings. |
