对 7种含“单”或“双”吡唑啉化合物在溶液和在固体器件 [ITO/ TPD/ TPBI-2 % EP/ TPBI/ Mg-Ag]中作为掺杂发光材料的电致发光特性进行了研究 .结果表明 ,由吡唑啉化合物所构成的器件具有优良的电致发光特性 .特别是在 5-位处联有芳基的双吡唑啉化合物 ,由于它们具有良好的成膜能力和较高的玻璃化转变温度 ,因此所制得的器件有很好的稳定性 .结果还表明 ,含双吡唑啉基化合物的荧光量子产率较含单吡唑啉基者为低 .由它们所构成器件的电致发光能力也大体反映出相同的趋势
The electroluminescent properties of seven “mono” or “double” pyrazoline compounds in solution and as a doped luminescent material in a solid device [ITO / TPD / TPBI-2% EP / TPBI / Mg-Ag] The results show that the device composed of pyrazoline compounds has excellent electroluminescent properties.Especially the bispyrazoline compounds with aryl group at the 5-position have the advantages of good film-forming ability and Higher glass transition temperature, the resulting device has good stability.The results also show that the fluorescent double-pyrazolyl-containing compounds yield fluorescence quantum yield than those with a single low-pyrazolyl by them The electroluminescent capabilities of the resulting devices also generally reflect the same trend
