【Abstract】 A series of 5-substituted 2-pyrazoline derivatives were synthesized and their physical properties were measured. The results indicate that the introduction of bulky groups into the pyrazoline ring increases the glass transition temperature (T g) of the compounds and changes the luminescent mechanism of the compounds. Differential scanning calorimetry (DSC) shows that the new pyrazoline derivative, 1,3-diphenyl-5-(9-phenanthrenyl)-2-pyrazoline (TAP7) has high T g of 96 ℃. The electroluminescent properties of this compound were measured. It is demonstrated that TAP7 is a good hole transport material and blue electroluminescent material with high thermal stability.更多还原
