摘要
合成了一系列 5位不同取代的 2 吡唑啉化合物 ,研究了取代基对吡唑啉化合物物理性质的影响 .结果表明 ,在吡唑啉化合物的 5位引入稠环取代基提高了吡唑啉化合物的熔点 ;同时 ,5位取代基的电位性质还影响着化合物的发光行为 .DSC差热分析结果给出 1,3 二苯基 5 (9 菲基 ) 2 吡唑啉 (TAP7)的玻璃化温度 (Tg)为 96℃ ;并研究了其在电致发光器件上的应用性能 .
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 degreesC. 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.
